Got a cool project that uses silly? Let us know!

Features

• Easy to install and use with dub
• No changes of your code are required to start using silly
• Seamless integration with dub test
• Named tests
• Multi-threaded test execution
• Filtering tests
• Colourful output

Getting started

Add silly to your project:

$ dub add silly

This should be it! Try to run tests:

$ dub test

If it succeeded then congratulations, you have just finished setting up silly! Make sure to add more tests and give them nice names.

Troubleshooting

Unfortunately, setup isn't that easy sometimes and running dub test will fail. Don't panic, most of the issues are caused by the quirks and twists of dub. Here are some suggestions on what to check first:

Make sure main() function isn't defined when built in unittest mode

So, instead of this:

void main() {

}

Do this:

version(unittest) {
	// Do nothing here, dub takes care of that
} else {
	void main() {

	}
}

Make sure there is no targetType: executable in unittest configuration in your dub.json/dub.sdl

Instead of this:

{
	...
	"configurations": [
		...
		{
			"name": "unittest",
			"targetType": "executable",
			...
		}
	]
}

Do this:

{
	...
	"configurations": [
		...
		{
			"name": "unittest",
			...
		}
	]
}

See #12 for more information.

Naming tests

It is as easy as adding a string user-defined attribute to your unittest declaration.

@("Johny")
unittest {
	// This unittest is named Johny
}

If there are multiple such UDAs, the first one is chosen to be the name of the unittest.

@("Hello, ") @("World!")
unittest {
	// This unittest's name is "Hello, "
}

Command line options

Silly accept various command-line options that let you customize its behaviour:

$ dub test -- <options>

Options:
  --no-colours                    Disable colours
  -t <n>      --threads <n>       Number of worker threads. 0 to auto-detect (default)
  -i <regexp> --include <regexp>  Run tests if their name matches specified regular expression. See filtering tests
  -e <regexp> --exclude <regexp>  Skip tests if their name matches specified regular expression. See filtering tests
  -v          --verbose           Show verbose output (full stack traces and durations)
  -h          --help              Help information

Filtering tests

With --include and --exclude options it's possible to control what tests will be run. These options take regular expressions in std.regex' format.

--include only tests that match provided regular expression will be run, other tests will be skipped. --exclude all of the tests that don't match provided regular expression will be run.

Using both options at the same time will produce unexpected results!
