testino
"small test" for node
A small test runner for a simple, small test framework. Because, hey, everyone writes a test framework in node, right?
Really, I just wanted to see what I could do in a day or two. I'm currently using it in node-ravendb for two reasons:
- vows was not catching non-AssertionError errors in the code
- I didn't want to use anything very big--I don't have that many tests
Approach
Keep things small (the main testino module is around 300 lines of code) and simple, support the assert module. Other than that, a few simple things:
- Each test fixture is created using testino.createFixture and then adding a tests member to that object
- You simply add a tests object as a member of the fixture, and each function is considered a test case
- Each test module should export the test fixture as it's module.exports and optionally consider adding a code snippet to run the tests if the file is run directly
Bonus: Since this is JavaScript, tests members can have a name that is a string, not just a legal function name, so have fun with spec-style test names!
These points are demonstrated in the Usage section below.
Usage
var testino = ;var assert = ; moduleexports = sampleTester = testino; sampleTestertests = { assert; } { assert; } { var actual = expected = null; assert; } { throw "This result should end up in the Other category"; }; // If the file is run directly, just run the test fixture with default outputif requiremain === module console;
and the output is:
$ node sample-test.jsTEST RESULTS FOR Sample Tester Total: 4 Passed: 2 Failed: 1 Other : 1 FAILED test details: thisTestShouldFail AssertionError: this test failed on purpsose OTHER test details: tests with unexpected errors end up in the "Other" category Error: This result should end up in the Other category
