Quick Start

Create a test class

You create a test class by implementing the tsUnit.ITestClass interface. Your test class can also be placed inside of a module.

module CalculationsTests {
    export class SimpleMathTests extends tsUnit.TestClass {

        private target = new Calculations.SimpleMath();

        addTwoNumbersWith1And2Expect3() {
            var result =, 2);

            this.areIdentical(3, result);

        addTwoNumbersWith3And2Expect5() {
            var result =, 2);

            this.areIdentical(4, result); // Deliberate error

Any functions in your test class are automatically run for you and the assertions used to pass or fail your tests. You can refer to class-level variables in your tests as the instance is preserved during testing.

Run the tests

// new instance of tsUnit
var test = new tsUnit.Test();

// add your test class (you can call this multiple times)
test.addTestClass(new CalculationsTests.SimpleMathTests());

// Use the built in results display

You can run the tests in the browser, or via a script engine. You can include these tests in your normal build and deploy routine either way by using a Coded UI test (or Selenium, or Waitn) or by using a script engine in your unit testing project.

Customise your output (only if you want to!)

If you want to customise the output, you can use the test result class returned from the run function:

var testResult =;

if (testResult.errors.lenth > 0) {
    alert('Oh dear!');

Grouping test results

You can optionally specify a name against your test class to group the test results:

test.addTestClass(new CalculationsTests.SimpleMathTests(), 'My Grouping');

This will then nest the results under the grouping. If you don't specify any groups, everything will be grouped under a single "Tests" group.
