aunit's Issues

Oops Actually Undefined Behaviour # AUnit freezes with strange arithmetic expression on Nano

Not a bug with AUnit.
Actually the 'divide by zero' was being optimised away by the compiler; changing to volatile int xxx caused it to crash well before the AUnit test. I thought I have this covered, but volatile make it clear that the problem is the good ol' 'divide by zero - undefined behaviour'

===

AUnit will freeze a Nano (only type tested) several lines before(? strange I know) the following test:
assertEqual(12345, (int)((long)32767/((long)5 / 9)/2));

#EDIT# same freeze issue happens on Mega #/EDIT#

A complete sketch to show freezing is:

#include <AUnit.h>

test(T9999_CrashesInArithmeticTest) {
  Print* pPrintDebug = &Serial;
  int xxx;

  if(pPrintDebug) { pPrintDebug->println(); pPrintDebug->flush(); }
  if(pPrintDebug) { pPrintDebug->print(F(" N ")); pPrintDebug->flush(); }
  xxx = 1/0;
  if(pPrintDebug) { pPrintDebug->print(F(" O ")); pPrintDebug->flush(); }
  xxx = (int)((long)12345/((long)5 / 9)/2);
  if(pPrintDebug) { pPrintDebug->print(F(" P ")); pPrintDebug->flush(); }
  xxx = (int)((long)32767/((long)5 / 9)/2);
  if(pPrintDebug) { pPrintDebug->print(F(" Q ")); pPrintDebug->flush(); }
  xxx =              (int)((long)32767/((long)5 / 9)/2);
  if(pPrintDebug) { pPrintDebug->print(F(" R ")); pPrintDebug->flush(); }
#if 1 // Toggle between 0 and 1 and watch the different results
  assertEqual(12345, (int)((long)32767/((long)5 / 9)/2));
#endif
  if(pPrintDebug) { pPrintDebug->print(F(" S ")); pPrintDebug->flush(); }
  assertEqual(1234, 2468);
}

void setup() {
  delay(1000); // wait for stability on some boards to prevent garbage Serial
  Serial.begin(115200); // The baudrate of Serial monitor is set
  while(!Serial); // for the Arduino Leonardo/Micro only
  Serial.println(F(__DATE__ " @ " __TIME__));
  Serial.println(F(__FILE__));

  Print* pPrintDebug = &Serial;
  int xxx;

  if(pPrintDebug) { pPrintDebug->println(); pPrintDebug->flush(); }
  if(pPrintDebug) { pPrintDebug->print(F(" A ")); pPrintDebug->flush(); }
  xxx = 1/2;
  if(pPrintDebug) { pPrintDebug->print(F(" B ")); pPrintDebug->flush(); }
  xxx = 1/0;
  if(pPrintDebug) { pPrintDebug->print(F(" C ")); pPrintDebug->flush(); }
  xxx = (int)((long)12345/((long)5 / 9)/2);
  if(pPrintDebug) { pPrintDebug->print(F(" D ")); pPrintDebug->flush(); }
  xxx = (int)((long)32767/((long)5 / 9)/2);
  if(pPrintDebug) { pPrintDebug->print(F(" E ")); pPrintDebug->flush(); }
}

void loop() {
  aunit::TestRunner::run();
}

Feature request (and patch) : filter test on command line

Hi Brian,

As I really need to run or debug only one test, I really miss the command line filtering option as it is possible with gtest.

So I've written this patch:

Because Test* are initialized before main() is called, I could not initialize mLifeCycle inside init() functions. The workaround was to wrap getLifeCycle.
I did not write a FilterTest just because I don't know how to unit test this feature :-(

I'd be cool to add this patch into the next release.

Best regards

Feature Request: Support 64 bit integer overloads

Would it be possible to add overload functions for "long long" and "unsigned long long" for integer comparisions such that this is supported:

uint64_t i = 5;
assertEqual(5ull, i);

Thank you

implement testF() and testingF() fixture macros

These are the versions of test() and testing(), but allow Fixture classes. Just like Google Test.

The feature is basically done on the develop branch. Probably need to double-check my unit tests, and document these methods in the README. Also add some more documentation about lack of assertXxx() short circuiting when they are used in a shared method. Although I just implemented delayed status resolution in all Assertion::assertXxx(), so that solves that problem for the majority of cases.

Might want to consider implementing a tearDown() method along with the testF() and testingF(), since the purposes of these is to reuse the test fixtures.

Feature Request: JUnit stylized output

One of the major reasons for using unit tests, is to enable better CI/CD practices. As such, it would be nice if AUnit came with the option of outputting results in a JUnit style so that the output artifacts can be used in things like GitLab test reports and other test reporting tooling.

create command line script that runs unit tests programmatically

Running one unit test using the Arduino IDE isn't so bad. But running 5 of them repeatedly, across multiple platforms (boards) using the IDE is painful.
Create a script that can:

compile the sketches (unit tests) programmatically
upload the sketch to the selected board
read the Serial output of AUnit and take note of whether the test succeeds or fails
collect the results of multiple unit tests and print them out as a summary at the end of the script

Issue when used as submodule

Hi. For some reasons, I can't use AUnit as git submodule. When installed using Arduino IDE all works fine.

In my setup I got

In file included from ExternalTests.cpp:12:0:
AUnitMetaTest.h:13:12: fatal error: AUnit.h: No such file or directory
compilation terminated.
exit status 1
Error compiling for board Arduino Pro or Pro Mini.

Steps to reproduce:

Create sketch in empty folder.
Init git repo.
Add AUnit as submodule.

 git submodule add [email protected]:bxparks/AUnit.git

Add minimal testing code in to the sketch.

#include "AUnit/src/AUnit.h"

test(submodule_include_test){
  int x = 1;
  assertEqual(x, 1);
}

Try to compile and get various errors.

add adapter header file for Google Test

In #28, @ciband refers to a Google Test adapter that he wrote:

https://github.com/ciband/Ark-Cpp/blob/feature/generate_private_key/test/IoT/gtest/gtest.h

It might be useful to other people, so we can host that file in this repo. I propose adding it here:

src/aunit/contrib/gtest.h

People can use it like this:

#include <AUnit.h>
#include <aunit/contrib/gtest.h>

#include <AUnitVerbose.h>
#include <aunit/contrib/gtest.h>

Questions for @ciband:

Are you agreeable to using MIT License for your code?
Why did you use:
- #define ASSERT_TRUE(x) assertNotEqual(static_cast<unsigned>(x), 0u) instead of:
- #define ASSERT_TRUE(x) assertTrue(static_cast<bool>(x)), or just
- #define ASSERT_TRUE(x) assertTrue(x) ?

potential mocking framework

hi @bxparks,

in issue #109, you said

The ability to mock out certain Arduino API functions that were not designed to be mocked

will it be possible to use a mocking framework like arduinofake in conjunction with aunit?

please advise.

thanks in advance,
rey malahay

Thanks.

allow timeout parameter to be specified on a per individual test basis

TestRunner has a global timeout.
It's easy enough to implement a timeout per-test, at the cost of one extra byte per test(), testing(), testF() and testingF().

hi there,

what is the correct way to configure the CPATH so that all of aunit's header dependencies are correctly referenced? my CPATH environment variable is currently configured as follows:

export CPATH=/home/reymalahay/Arduino/libraries/AUnit/src

but i keep getting the error listed below when running my tests in EpoxyDuino.

Add ability to do case insensitive string compare

I am using AUnit with a GTest interface wrapper to allow my unit tests to run on desktop OS as well as Arduino. I have the following adapter:

#include <AUnit.h>

#define TEST(category, name) test(category##__##name)

#define ASSERT_EQ(e, a) assertEqual(static_cast<decltype(a)>(e), a)
#define ASSERT_NE(e, a) assertNotEqual(static_cast<decltype(a)>(e), a)
#define ASSERT_STREQ(e, a) assertEqual(static_cast<decltype(a)>(e), a)
#define ASSERT_STRNE(e, a) assertNotEqual(static_cast<decltype(a)>(e), a)
#define ASSERT_STRCASEEQ(e, a) // ??
#define ASSERT_STRCASENE(e, a) // ??

#define ASSERT_TRUE(x) assertNotEqual(static_cast(x), 0u)
#define ASSERT_FALSE(x) assertEqual(static_cast(x), 0u)

It would be nice to have an easy way to do a case insensitive string compare similar to what GTest does. If the framework can already do this then a point in the right direction is appreciated.

Thanks for the wonderful framework.

Increase size of TimeoutType from 8 to 16 bits; maybe allow per test timeouts.

Timeout limit of 255 seconds too small; I wanted around 10 minutes so set it to 999 (no compiler warning) and of course it timed out.
I suggest that TimeoutType be changed from uint8_t to uint16_t. I have not checked what follow-on changes may be needed.

PS Maybe allow per test timings?

support arduino:samd Core using new Arduino API for versions >= 1.8.10

The arudino:samd core migrated to the "new Arduino API" at version >= 1.8.10. The new Arduino API has a number of backwards compatibility issues, and breaks AUnit. See arduino/ArduinoCore-samd#587 for more details. Some of this might be fixable. This is the tracking bug.

print out how long the test suite ran

TestRunner should print out how long the test suite ran. This becomes more interesting as the test suite gets bigger and bigger.

support assertEqual() on (void*) pointers

I recently wrote a unit test where I wanted assertEqual() to work on pointers. The workaround was to cast the pointers to uintptr_t from #include <stdint.h>.

I think a cleaner solution could be implemented by adding support for

assertEqual(void*, void*)

which could be accomplished by adding 2 overloads to Assertion.h:

    bool assertion(const char* file, uint16_t line, void* lhs,
        const char *opName, bool (*op)(void* lhs, const void* rhs),
        void* rhs);

    bool assertionVerbose(const char* file, uint16_t line, void* lhs,
        const __FlashStringHelper* lhsString, const char* opName,
        bool (*op)(void* lhs, void* rhs),
        void* rhs, const __FlashStringHelper* rhsString);

I think c-strings (in all its various forms) would match the assertEqual(const char*, const char*) version, while allowing other pointers to bind to the assertEqual(void*, void*) version.

GoogleTest does not have the overload problem because ASSERT_EQ() always compares pointers, even for c-strings. It uses a separate set of macros (ASSERT_STREQ(), ASSERT_STRNE() and their case-insensitive versions) for c-string comparisons.
https://github.com/google/googletest/blob/master/googletest/docs/primer.md#string-comparison

(If I had not aimed for ArduinoUnit compatibility, I probably would have followed the GoogleTest convention.)

Support assert* in (anonymous) callbacks

First of all, thank you so much for this great library!!!

I have the following test code:

test(parseEvent) {
  String eventText = String("BEGIN:VEVENT\nEND:VEVENT");
  parser.parseEvent(eventText, [](ICalParser::Event event) {
    assertEqual(123, event.startDate);
  });
}

Since the assertEqual is called within the callback function I'm getting the following compile error:

In file included from .piolibdeps/AUnit_ID2778/src/AUnit.h:53:0,
from src/main.cpp:2:

Is it possible that I can do an assertion in a callback?

Error When Running AUnit: fatal error: AUnit.h: No such file or directory

I just used this library to write unit tests for my Arduino codebase and I integrated it into GitHub Actions as per the test examples given. When running, I get the following error:

MotorControlWithEncoder.ino:6:10: fatal error: AUnit.h: No such file or directory
    6 | #include <AUnit.h>
      |          ^~~~~~~~~

Any idea how I could make the GitHub actions know about AUnit being used? In my Makefile, I have the following:

APP_NAME := MotorControlWithEncoder
ARDUINO_LIBS := AUnit
include ../../../UnixHostDuino/UnixHostDuino.mk

support 2 argument versions of test() and testing() macros

AUnit inherited the test() macro from ArduinoUnit and accepts only 1 argument. In GoogleTest, the TEST() macro takes 2 arguments like this: TEST(caseName, testName). The full test name is the concatenation of the two arguments (separated by an underscore), like this caseName_testName.

If a single program contains numerous unit tests which test multiple classes, being able to organize the unit tests into test suites becomes useful. I will add a 2-argument version of test() like this: test(suiteName, testName), overloading the 1-argument version of the same name. I learned a few months ago that it is possible to overload macros in the C preprocessor using different number of arguments.

Note that the test(suiteName, name) macro is different than the testF(className, name) macro. In fact, with both macros taking 2 arguments, these 2 macros become more equivalent to their GoogleTest counterparts TEST() and TEST_F().

The overloading needs to be implemented for the following macros: test(), testing(), externTest() and externTesting().

This change is fully backwards compatible because old testing code will automatically use the 1-argument versions of these methods.

implement assertNoFatalFailure() macro

Google Test has an ASSERT_NO_FATAL_FAILURE() macro which calls the code in the argument (usually a helper method), then returns if that code caused the current test to resolve (failed, expired, skipped, etc). I think this is a pretty easy macro.

better messages for assertTrue() and assertFalse()

assertTrue(x) and assertFalse(x) are written in terms of assertEqual(x, true) and assertEqual(x, false). Since AUnit does not capture and print the lhs and rhs strings, the assertion messages are confusing, looking something like this:

Assertion failed: (0) == (1), file Test.ino, line 1236.

It's not possible to tell which was the one given in the argument of assertTrue() and assertFalse(). We should use a different, more informative message for these.

(Also note that part of the problem could be that Serial.print(true) prints 1, not true.)

Error in test headers?

Hi, this is the first time I'm using this lib, and I'm also a newbie in the Arduino world, so maybe I missed something, but I got errors to the .h files while compiling.

These were the errors:

Arduino: 1.8.19 (Windows 8.1), Board: "ESP32 Wrover Module, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), QIO, 80MHz, 921600, None"

Current version leaves out the lhs and rhs strings of various assertXxx() statements, saving about 30-50% flash memory compared to ArduinoUnit. But these strings are actually very useful for debugging. Considering adding them back in, but offer 2 headers for the end-user:

AUnit.h (contains lhs and rhs strings)
AUnitTiny.h (AUnitShort.h, AUnitTerse.h?), which don't have these strings

Since these assertXxx() methods are actually#define macros, it should be possible to allow the user to select the version at compile time, and the linker should remove all the methods which aren't used by the given program. This allows the user to choose to pay for the flash memory or not, depending on the project. (Many of my unit tests hit close to 30kB even without the lhs and rhs strings).

allow temporary disabling of tests using "DISABLED_" prefix?

Google Test allows temporarily disabling a test if the name is prefixed with "DISABLED_". I've occasionally found myself wanting this feature while debugging existing unit tests. The current workarounds are:

use TestRunner::exclude()
use #if 0 / #endif pairs
use /* */ comment lines

I'm assuming it's something to do with unitduino. Not familiar with it though.

"unsigned" not implemented ?

The following program produces a compile error:
error: call of overloaded 'assertion(const char [15], int, unsigned int&, const char [3], <unresolved overloaded function type>, int)' is ambiguous

#line 2 "test_aunit.ino"
#include <AUnit.h>

  Serial.begin(115200);
}

  assertEqual(i, 1);
}

Comparing float values

Hello,

I'm encountering issues when comparing float values, since I get results similar to the following:
Assertion failed: (44.30) == (44.30)

My understanding is that AUnit does not provide assert functions specifically designed for floats and doubles (the equivalent of ASSERT_FLOAT_EQ & co of the Google Test framework)

Currently I am using the following workaround:

float epsilon = 0.00001;
assertTrue(fabs(44.3 - testValue) < epsilon);

Am I missing something?

Better documentation using a simple use case

Could the documentation be made a little bit better by doing a step-by-step instruction using a simple use case (could be as simple as the Arduino blink example), run the unit tests in a GitHub action?

Test fixture implementation following example didn't work

I tried to implement a test fixture (https://github.com/arjuna-dev/AUnit/blob/develop/examples/fixture/fixture.ino) but found that I needed to add aunit:: to TestOnce for it to work (so aunit::TestOnce) when inheriting from TestOnce. I'll make a pull-request with this minimal change

Error When Running AUnit Simple Example

I created a simple AUnit example as below:

When I ran it via GitHub action, I got the following error:

/usr/bin/ld: /tmp/MotorControlWithEncoder.out.m5fOP5.ltrans0.ltrans.o: in function `unixhostduino_main':
<artificial>:(.text+0x4594): undefined reference to `setup'

make: Leaving directory '/home/runner/work/navo-hardware-libs/navo-hardware-libs/test'
make: *** [Makefile:8: tests] Error 2

Any ideas what this could mean? Do I need to add a auniter.ini file that contains the configurations? I do not have that yet as I did not find any instructions.

add optional message string to assertXxx() macros

When assertXxx() is used in a common helper function, or in a for-loop, it would be really nice to be able to add additional message strings into its output, so that we can figure out where the code breakage was more easily. (AUnit doesn't use exceptions, like Google Test and ArduinoUnit, so can't give the stack trace.)

allow TestRunner to be substituted

TestRunner was designed so that it could be replaced by a user-defined class if needed. But I haven't exposed this feature. Is anyone interested in this feature?

Can´t compile my project when using classes with a separate .cpp file

I am unable to compile any testing project that tests a class with separate .h and .cpp files.

I have tried with standard test macros, testF macros, with object definition in several places of the code, and changed around library inclusion order without any effect whatsoever.

I would suspect of a Linker order problem, but I can't find any makefile to see if this might be.

By having a single header class definition the issue is solved, yet this is not recommended tipically, as one would want to have separate declarations and definitions.

Is there any workaround to this. Can this be fixed somehow?

Great project otherwise. Hope to see much more from this.

Testing with unitduino or UnixHostDuino will always exit on success

No matter if tests fail, if the tests are ran in a CI/CD platform, like gitlab runner, it won't be able to detect a failure. I believe it's related with exit(0) instruction in TestRunner.cpp line 113.

ASSERT_EQ does not work with refrence

ASSERT_EQ from aunit/contrib/gtest.h does not compile when reference is used:

    uint8_t& ref = a[2];
    ASSERT_EQ( 0x83, ref );

Compiler message is:

invalid static_cast from type 'int' to type 'uint8_t& {aka unsigned char&}'

removing the cast from the macros make it compile.

#define ASSERT_EQ(expected, value) assertEqual((expected),(value))

May be there is a better (improved) version instead of static_cast<decltype(a)>(e)

Add official support for ESP32

If you are looking to add support for more boards, please consider ESP32. If it doesn't work already, it wouldn't take much.

We are using this for our project on ESP32 (see #23)

Thank you.

Feature Request: Support assertIsNull

Would it be possible to support the "isNull" concept with pointers? If so, could it play nice with std::nullptr_t such that you can write this:

const char* s = nullptr;
assertIsNull(s);

Thank you

test macro not working

I am using the test macro but I get this error message: expected an expression. Is this a problem?

    TempSensorDummy temp(-1);

    assertEqual(temp.getTemperature(), 20);
    assertEqual(temp.getHumidity(), 20);
    assertEqual(temp.getData(), nullptr);

Missing WProgram.h

Hi Brian

My unit tests are broken due to WProgram.h missing (here)

This files has gone when I have acecpted your PR on EspMock.

I may be wrong as this is the first time I'm using EPOXY_CORE as I wanted my unit tests to pass since this modification.

Best regards

How do you test analogRead and digitalRead?

merge test()/testF() and testing()/testingF() into each other

With some C-preprocessor hackery, it's possible to merge the 1-argument macro and the 1-argument macro into a single macro. Not sure if this is worth it or not.

support teardown() method, analogous to setup()

Most unit testing frameworks support the teardown() method, analogous to setup(). ArduinoUnit did not have this, and I thought that in the limited memory size of an Arduino MCU, the teardown() would not be needed. However, upon dogfooding the new testF() macros in my tests, I've found myself wanting to have a teardown() method.

The teardown() would need to be virtual, so would consume 2 extra bytes (on 8-bit AVR, 4 bytes on 32-bit processors) for each test. For a large test suite (30-40 tests), I thought that an extra 80 bytes would not be worth it. However, I've found that the extra code necessary to work around the lack of a teardown() probably consumes more than the 80 extra bytes in the v-table. So in the end, I think the teardown() method would actually save flash memory for a large test suite.

Note about the naming convention: JUnit uses setUp() and tearDown(), Google Test uses SetUp() and TearDown(). AUnit and ArduinoUnit uses a lowercase setup(), so I think the tear down method will have to be named lower case teardown() to be internally consistent.

FeatureRequest: support Arduino Nano Every (ATmega4809)

My tests (and example tests) compile correct for Arduino UNO (ATmega328P) but NOT for Arduio Nano Every.

Github action for "pull_request" as well as "push"?

Thanks for creating this library! I has saved me from myself several times already.

Recently someone had a good idea for my library and submitted a pull request for it ( philj404/SimpleSerialShell#12 ).

They followed good practices on GitHub and created a fork of my repository, made their changes and submitted their pull request back to me.

When I enabled the action (for first time contributors) the pull request did not run aunit tests on their submission. The build checks ran as I expected.

I think the reason the aunit tests did not run is that the GitHub Action is set up to only run on "push". Since the changes were pushed to a fork, they did not run on "push". Since aunit_tests.yml only runs on "push", creating the pull request did not trigger a run.

So, I have a couple questions:

Does it even make sense to run unit tests on a pull request from a code fork (as a pre-check)?
I made a copy of aunit_tests.yml for my library's GitHub action. (Since it is a copy I have not kept up to date with later improvements.) I have modified my copy to run on pull requests. Would it make sense for the master example of aunit_tests.yml to run on pull requests by default?

Thanks again for providing such a useful way to run unit tests.

allow customization of Assertion::printAssertionMessage()

In theory, it would be really nice to allow the end-user to customize the output of:

Assertion::printAssertionMessage()
MetaAssertion::printAssertionTestStatusMessage()

However, there are 16 overloaded versions of Assertion::printAssertionMessage(). If we were to make them virtual, each of them would occupy 2 bytes (AVR) in the v-table. And then, every test(), testing(), testF() and testingF() macro generates a new subclass of TestOnce or TestAgain, which means that each of those objects would take ~32 extra bytes of flash memory. For a large test suite (~30-40 tests), that's about 1kB of extra flash, which is significant.

The alternative is to use 17 function pointers, instead of virtual functions. I'm not convince that this feature is worth the extra complexity...

Your recommended test for nullptr fails for me. Is this my problem or yours? <EDIT it's mine/>

When I compile (cf https://github.com/bxparks/AUnit#PointerComparisons)

test(nullPointer) {
  const int aa[] = {1, 2};
  assertEqual(aa, nullptr);
}

inserted into your Examples - Aunit - basic, It fails. (Nano selected)
I believe I'm running your master branch of AUnit f47bd08 from 16 months ago.
I have a symbolic link in libraries to a local git repo of your AUnit
Is this something bad I've done (I have some local mods to ./arduino15 tables etc), or is the problem 'at your end'?
A work around is replace nullptr with (void*)nullptr
