Venom: Support for .yml & .yaml extensions

[scraly]

Observation

For this PR I started from an observation:

By default, venom CLI take in account .yml extension.
If it found .yml file, no need to specify them in the venom run command line:

$ tree /Users/avache/tmp/venom/2 ; go run main.go run /Users/avache/tmp/venom/2
/Users/avache/tmp/venom/2
└── testsuite.yml

0 directories, 1 file
	  [trac] writing venom.log
 • APIIntegrationTest (/Users/avache/tmp/venom/2/testsuite.yml)
 	• GET-http-testcase-with-5-seconds-timeout SUCCESS

But it does not support .yaml extension file:

$ tree /Users/avache/tmp/venom/1 ; go run main.go run /Users/avache/tmp/venom/1
/Users/avache/tmp/venom/1
└── testsuite.yaml

0 directories, 1 file
	  [trac] writing venom.log
no yml file selected
exit status 2

But:

• YAML recommend that we use .yaml extension (https://yaml.org/faq.html)
• We can see people using .yml or .yaml extension for YAML files, depending all the time

And: « no yaml file selected », the text message is not very true because we have a YAML file but not in the extension it wanted to :) .

Sometimes in the code we supports both:

for _, fp := range fpaths {
			switch ext := filepath.Ext(fp); ext {
			case ".yml", ".yaml":
				filePaths = append(filePaths, fp)
			}
		}

But not in the example I show previously for the venom run command support by default.

Solution

So I recommend that Venom need to supports both .yml and .yaml extensions, not only .yml by default, all the time.

New behavior after the feature coded in the PR

Both .yml and .yaml are now supported by default:

$  tree /Users/avache/tmp/venom/1 ; go run main.go run /Users/avache/tmp/venom/1
/Users/avache/tmp/venom/1
└── testsuite.yaml

0 directories, 1 file
	  [trac] writing venom.log
[/Users/avache/tmp/venom/1]
 • APIIntegrationTest (/Users/avache/tmp/venom/1/testsuite.yaml)
 	• GET-http-testcase-with-5-seconds-timeout SUCCESS

$  tree /Users/avache/tmp/venom/2 ; go run main.go run /Users/avache/tmp/venom/2
/Users/avache/tmp/venom/2
└── testsuite.yml

0 directories, 1 file
	  [trac] writing venom.log
[/Users/avache/tmp/venom/2]
 • APIIntegrationTest (/Users/avache/tmp/venom/2/testsuite.yml)
 	• GET-http-testcase-with-5-seconds-timeout SUCCESS
