A set of regression tests for Radare2 (http://radare.org).

Originally based on work by and now in collaboration with pancake.

• new/: New testsuite written in NodeJS.
• unit/: Unit tests (written in C, using minunit).
• bins/: Sample binaries.

• Radare2 installed (and in $PATH or set the R2 environment).
• Valgrind (optional).
• nodeJS 8 or above

• To run all tests, use make -k all.
• To execute only the unit tests use make -k unit_tests.
• To execute only the regressions tests use make -k js-tests.
• To execute and autofix a specific set of tests use node node_modules/node-r2r/bin/r2r.js -i db/XXXX/YYYY within new directory, this will provide a dialog in which you can ask the program to replace the expected output with the current output of radare2.

A test can have one of the following results:

• success: The test passed, and that was expected.
• fixed: The test passed, but failure was expeced.
• broken: Failure was expected, and happened.
• failed: The test failed unexpectedly. This is a regression.

Please do not post Radare2 bugs on the r2-regressions github tracker. Instead use the official r2 tracker:

Example tests for db/asm/*:

General format:
type "assembly" opcode [offset]

	type:
		* a stands for assemble
		* d stands for disassemble
		* B stands for broken
		* E stands for cfg.bigendian=true

	offset:
		Some architectures are going to assemble an instruction differently depending
		on the offset it's written to. Optional.

Examples:
a "ret" c3
d "ret" c3
a "nop" 90 # Assembly is correct
dB "nopppp" 90 # Disassembly test is broken

You can merge lines:

adB "nop" 90

acts the same as

aB "nop" 90
dB "nop" 90

    The filename is very important. It is used to tell radare which architecture to use.

    Format:
    arch[[_cpu]_bits]

Example:
x86_32 means -a x86 -b 32
    arm_v7_64 means what it means

The JSON tests db/new/json are executed on 3 standard files (1 ELF, 1 MachO, 1 PE). The tests need to be working on the 3 files to pass.

Example commands tests for the other new/ folders:

NAME=test_db
FILE=/../bins/elf/ls
CMDS=<<EXPECT
pd 4
EXPECT=<<RUN
        ;-- main:
        ;-- entry0:
        ;-- func.100001174:
        0x100001174      55             Push rbp
        0x100001175      4889e5         Mov  rbp, rsp
        0x100001178      4157           Push r15
RUN

• NAME is the name of the test, it must be unique
• FILE is the path of the file used for the test
• ARGS (optional) are the command line argument passed to r2 (e.g -b 16)
• CMDS are the commands to be executed by the test
• EXPECT is the expected output of the test

You must end the test by adding RUN keyword

• Never use shell pipes, use ~
• dont use pd if not necessary, use pi
