Test Coverage Error

[icywaffle]

The first issue that I ran into, trying to copy the Booking example in order to use go test for full coverage. When I was trying to use the Get method for the testing suite, it would instantly give me a

revel  panic.go:522: Recovered error in startup                error="runtime error: invalid memory address or nil pointer dereference"
panic: runtime error: invalid memory address or nil pointer dereference [recovered]
        panic: Fatal error in startup
[signal 0xc0000005 code=0x0 addr=0x8 pc=0x631651]

After a few hours of debugging, I finally realized that this was actually the correct response for the test, because it was actually the Get method was appending the wrong URI, causing a panic into a test failure.

What I had to do was actually use GetCustom, and used this instead.

import(
	"testing"
	"github.com/revel/modules/server-engine/gohttptest/testsuite"
)
func TestForGETRequests(t *testing.T) {
	suite := testsuite.NewTestSuite(t)

	url := "http://" + suite.Host() + "/somePath"
	suite.GetCustom(url)
}

However, the Get method works normally using the normal test format from the main page tutorial, but I think it's better to use this way to get test coverage.

I was wondering why this was an issue, and if anyone ran into this issue too, I hope it helps.

At a closer look, GetCustom looked like it worked, but it actually does nothing. We don't get a response to decode, because there was nothing that decoded the response. When adding .Send() method at the end of it, it panics again.

Here is the stack trace,

This also doesn't work for any of the other HTTP methods.

@icywaffle did you find a solution? If not, can you reproduce the issue with a new revel app (revel new testapp)?
