test: validate go templates with go

[qvalentin]

• Some testnames are still ugly
• corpus_test.go:29: template: template:2: missing value for block clause -> it is working, I found a bug ;)
• ci

Suggested change

	partsWithEmptyParts := TESTCASE_SEPERATOR.Split(content, -1)
	parts := []string{}
	// remove empty parts
	for i := 0; i < len(partsWithEmptyParts); i++ {
	if partsWithEmptyParts[i] != "" {
	parts = append(parts, partsWithEmptyParts[i])
	}
	}
	parts := TESTCASE_SEPERATOR.Split(content, -1)
	// remove empty parts
	index := 0
	for _, str := range parts {
	if str != "" {
	parts[index] = str
	index++
	}
	}
	parts = parts[:index]

idk, sometimes the simplest loop is the best loop.

Really nice addition to the project!

Suggested change

	INPUT_OUTPUT_SEPERATOR = regexp.MustCompile("\n(---)\n")
	INPUT_OUTPUT_SEPERATOR = regexp.MustCompile("\n(-+)\n")

So a test doesn't fail to parse if it includes more than 3 dashes.

[guilhas07]

Maybe we should just set testParts to something like this:

Suggested change

	fmt.Printf("Error parsing %s: Testcase has invalid format %s\n", filename, testName)
	continue
	testParts = []string{"", ""}

and check in the testTemplate against input so we get a test failure from a bad formatted test.

With this change, I can see a test failure easily:
--- FAIL: TestCorpus/corpus/actions.txt:_invalid_comments (0.00s)
(although this stops failing once the regex change suggested above is applied).

Suggested change

	TESTCASE_SEPERATOR = regexp.MustCompile("(?m)^(=+)$")
	INPUT_OUTPUT_SEPERATOR = regexp.MustCompile("\n(---)\n")
	TRIM_TESTCASE_SEPERATOR = regexp.MustCompile("^(=+)\n")
	TESTCASE_SEPARATOR = regexp.MustCompile("(?m)^(=+)$")
	INPUT_OUTPUT_SEPARATOR = regexp.MustCompile("\n(---)\n")
	TRIM_TESTCASE_SEPARATOR = regexp.MustCompile("^(=+)\n")
