3. **断言**
**断言功能列表：**
1. **引入uitest框架**
```
import {Driver,ON,Component,Uiwindow,MatchPattern} from '@ohos.UiTest'
```
2. **引入ability**
```
import AbilityDelegatorRegistry from '@ohos.app.ability.abilityDelegatorRegistry';
```
3. **添加启动应用准备**
```
beforeAll(async (done: Function) => {
// Presets an action, which is performed only once before all test cases of the test suite start.
// This API supports only one parameter: preset action function.
let abilityDelegator = AbilityDelegatorRegistry.getAbilityDelegator();
try {
await abilityDelegator.startAbility({
bundleName: 'com.example.myapplication',
abilityName: 'EntryAbility'
});
} catch (exception) {
console.info(TAG, `StartAbility_001 exception = ${JSON.stringify(exception)}`);
expect().assertFail();
}
done();
})
```
4. **添加测试用例**
```
it('StartAbility_001', 0, async (done: Function) => {
console.info(TAG, 'StartAbility_001 begin');
let driver = Driver.create();
await driver.delayMs(100);
await driver.assertComponentExist(ON.text('Hello World'));
// find component by text
let button: Component = await driver.findComponent(ON.text('Hello World').enabled(true))
// click component
await button.click()
// get and assert component text
let content: string = await button.getText()
expect(content).assertEqual('Hello World')
done();
})
```
TestFinished-ResultCode: 0
TestFinished-ResultMsg: your test finished!!!
user test finished.
```
7. **覆盖率结果**
8. **为啥没覆盖到，可以点击具体部分查看**
**红色部分就是没覆盖部分，其实就是生命周期没覆盖，只测试了启动（也就是前台Foreground，没有后台Background，也没有load失败）所以生命周期的测试不完整。**
