Describe the bug
newly cloned repo from main branch fails to execute some of the tests.
To Reproduce
Steps to reproduce the behavior:
try to compile handler_test.go
Expected behavior
compiles with no errors
Actual Behavior
Code does not compile. in the readme file, it is still mentioned, that mocha.New(t) or mocha.NewSimple() is to be used to instantiate mocha instance to facilitate tests, however these methods are not found.in other tests, e.g. mhttp_test.go a different way to instantiate mocha is used, namely `NewAPI
also I can't find AddMocks() in current code.

Describe the bug
I'm trying to use mocha to mock a .tar.gz artifact download, but the binary response body is corrupted.
The error occur because the Scanner used to write the mocked body, because "Successive calls to the Scanner.Scan method will step through the 'tokens' of a file, skipping the bytes between the tokens.", and it causes an error when I try to read the file.
The error occurs because of a behavior of the bufio.Scanner used to write the mocked body into the response. The library doc says that "successive calls to the Scanner.Scan method will step through the 'tokens' of a file, skipping the bytes between the tokens" and, as the default token is a \n character, causes the corruption
I'm using github.com/vitorsalgado/mocha/v3 v3.0.2
To Reproduce
package whatever
var (
//go:embed test/*.tar.gz
testFiles embed.FS
)
func TestErrorSample(t *testing.T) {
m := mocha.New(t)
m.Start()
content, _ := testFiles.ReadFile("test/any_file.tar.gz")
m.AddMocks(mocha.Get(expect.URLPath("/test.tar.gz")).
Reply(reply.OK().Body(content)))
client := resty.New().SetBaseURL(m.URL())
resp, err := client.R().Get("/test.tar.gz")
if err != nil {
t.Fatal(err)
}
assert.Equal(t, content, resp.Body()) // Not equal
}Expected behavior
I expect that the response body be equal to the configured body.

Environment (please complete the following information):
Additional context
A pattern I currently follow for all my Go tests is to store JSON response bodies in e.g testdata/all_users.json or testdata/europe_users.json and so on.
The testdata directory is considered the idiomatic way to do this in Go.
It would be super convenient if I could do something like the following, with an error/failure if the file does not exist:
m := mocha.New(t).CloseOnCleanup(t)
m.Start()
m.AddMocks(mocha.
Get(expect.URLPath("/users")).
Reply(reply.OK().BodyFile("testdata/all_users.json)))Currently I'm using a separate helper function to read the files and pass the string in using BodyString(...)
Describe the bug
I'm trying to setup a mock server with 2 replies for the same URL Path, but all requests fail with 418 - I'm a teapot. From what I could gather from the lib examples, I believe this should have worked
To Reproduce
Run the following test
package main
import (
"net/http"
"testing"
"github.com/stretchr/testify/assert"
"github.com/vitorsalgado/mocha/v3"
"github.com/vitorsalgado/mocha/v3/expect"
"github.com/vitorsalgado/mocha/v3/reply"
)
func TestSeqReply(t *testing.T) {
m := mocha.New(t)
m.Start()
m.AddMocks(mocha.Get(expect.URLPath("/test")).Reply(reply.Seq().Add(reply.Unauthorized(), reply.OK())))
req, _ := http.NewRequest(http.MethodGet, m.URL()+"/test", nil)
res, err := http.DefaultClient.Do(req)
assert.Nil(t, err)
assert.Equal(t, 401, res.StatusCode)
res, err = http.DefaultClient.Do(req)
assert.Nil(t, err)
assert.Equal(t, 200, res.StatusCode)
}
Expected behavior
Test should run with no errors

Describe the bug
If you submit a request to the Mocha server without a body, and you have a matcher with a body match, mocha gets a memory panic
To Reproduce
Create mocha server
func TestMochaNil(t *testing.T) {
m := mocha.New(t, mocha.Configure().Addr("localhost:8080").Build()).CloseOnCleanup(t)
// Start mock CCM API
m.Start()
m.AddMocks(
// Missing data for runConfig
mocha.Post(expect.URLPath("/test")).
Body(expect.JSONPath("data", expect.ToContain("aaa"))).
Reply(reply.OK().BodyJSON("hello world")),
// Metrics cost mapper
mocha.Get(expect.URLPath("/test")).
Reply(reply.OK().BodyJSON("hello world")),
)
url := "http://localhost:8080/test"
// Create a new HTTP client
client := &http.Client{}
// Create a new GET request
req, err := http.NewRequest("GET", url, nil)
if err != nil {
fmt.Println("Error creating request:", err)
return
}
// Send the request
resp, err := client.Do(req)
if err != nil {
fmt.Println("Error making request:", err)
return
}
defer resp.Body.Close()
}
Expected behavior
At the very least, when the check for method "Post" fails, the loop of expect checks should short stop before the body check ever happens.
But the body check should fail if the body is nil
