Create a component harness
> Author: Thomas Laforge
### Information
The goal of this challenge is to create a test harness for `slider.component.ts`. The harness file, `slider.harness.ts`, has already been created.
The following API needs to be implemented:
```ts
async clickPlus(): Promise ;
async clickMinus(): Promise;
async getValue(): Promise ;
async getMinValue(): Promise;
async disabled(): Promise;
async setValue(value: number): Promise;
```
Additionally, you should create a `HarnessPredicate` with the default predicate and the `minValue` property.
```ts
static with(
this: ComponentHarnessConstructor,
options: SliderHarnessFilters = {}
): HarnessPredicate;
```
Lastly, you will need to create the test suite for `app.component`. Some default tests have already been written, but feel free to add as many tests as you want and create as many harness methods as you need.
