# tests
A unit test framework
## Defining tests
Tests are registered as event handlers. They will automatically run once ``on start`` is finished.
```blocks
tests.test("lgB set speed 10", () => {
motors.largeB.setSpeed(10);
2018-02-15 01:05:31 +01:00
pause(100)
2017-12-19 16:07:50 +01:00
tests.assertClose("speedB", 10, motors.largeB.speed(), 2)
});
```
## Assertions
The library has various asserts that will register fault. Note that since exceptions are not available, assertion failure **do not** stop the program execution.
* **assert** checks a boolean condition
```blocks
tests.assert("speed positive", motors.largeB.speed() > 0)
```
* **assert close** checks that a numberical value is within a particular range
```blocks
tests.assertClose("speed", motors.largeB.speed(), 10, 2)
```
```package
tests
```
