Flixel Unit Tests
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
This is a unit test project using [munit](https://github.com/massiveinteractive/MassiveUnit). It's good practice to add tests for fixed bugs or new features.
|
||
|
|
|
||
|
|
TODO Make sure the unit tests are automatically run on GitHub Actions.
|
||
|
|
|
||
|
|
There's a 1:1 mapping between `.hx` files in `source/` and the unit test project - tests for `funkin.Conductor` go into `funkin.ConductorTest` etc.
|
||
|
|
|
||
|
|
### Building
|
||
|
|
|
||
|
|
Run one of the `test-*.hxml` files in this directory to run the tests on that specific target, e.g. `haxe test-cpp.hxml`. Currently supported are:
|
||
|
|
|
||
|
|
- `web` (HTML5)
|
||
|
|
- `cpp` (Native)
|
||
|
|
|
||
|
|
Alternatively, this can be done from within Visual Studio Code - (`F1` -> `Tasks: Run Task` -> Choose the target to test).
|
||
|
|
|
||
|
|
#### Adding Tests
|
||
|
|
|
||
|
|
- Run `haxelib run munit create com.FooBarTest -for com.Foo`
|
||
|
|
- Use `@:allow(full.package.name.ClassName)` to allow a test class to call private functions.
|
||
|
|
- Use `mockatoo.Mockatoo.mock(ClassName)` to mock a class. See [Mockatoo docs](https://github.com/misprintt/mockatoo).
|
||
|
|
|
||
|
|
#### Functions
|
||
|
|
|
||
|
|
- `@Before` functions are named `before()`
|
||
|
|
- Each `@Test` function starts with `test` and describes what exactly it tests. This can lead to long function names like `FlxEmitter#testStartShouldNotReviveMembers()` and serves as self-documentation.
|
||
|
|
- Another thing that helps with self-documentation is adding a comment for tests that are related an issue on GitHub.
|
||
|
|
|
||
|
|
```haxe
|
||
|
|
@Test // #1203
|
||
|
|
function testColorWithAlphaComparison()
|
||
|
|
```
|
||
|
|
|
||
|
|
### `FunkinTest` base class
|
||
|
|
|
||
|
|
Test classes extend `FunkinTest`, which is a base class with some utility functions for testing.
|
||
|
|
|
||
|
|
### `step()`
|
||
|
|
|
||
|
|
`step()` advances the `FlxGame` exactly one step. This is useful for tests that depend on game time advancing / `FlxGame#step()` being executed, such as physics of `add()`ed objects, state switches, or just time passing for tweens or timers.
|
||
|
|
|
||
|
|
There are two parameters:
|
||
|
|
- `steps` - specifies the amount of steps to advance (defaults to 1)
|
||
|
|
- `callback` - an optional callback function that is executed after each step
|
||
|
|
|
||
|
|
### `testDestroy()`
|
||
|
|
|
||
|
|
`testDestroy()` tests whether an `IFlxDestroyable` can safely be `destroy()`ed more than once (null reference errors are fairly common here). For this, `destroyable` has to be set during `before()` of the test class.
