7.Schematics 单元测试 1
jasmine
- 执行命令
ts-node -P ./tsconfig.spec.json ./node_modules/jasmine/bin/jasmine --config=jasmine.json - 无测试覆盖率,需要配合 karma+一堆插件实现
单独覆盖率的话可以用 nyc
- ng 指定
依赖包
- jasmine
- @types/jasmine
- ts-node
jest
- 执行命令
jest - 初始化命令
jest init - ts 配置友好
- 带测试覆盖率
-
自带兼容 jasmine 策略
testRunner
- 运行速度稍慢
依赖包
- jest
- @types/jest
- ts-jest
- ts-node
测试方法(jasmine,jest 相同)
// 执行原理图首先需要指定collection,然后再运行某个原理图
describe('unit-demo', () => {
it('运行内部原理图', async () => {
let runner = new SchematicTestRunner('test', require.resolve('../collection.json'));
// 这里
let tree = await runner.runSchematicAsync('unit-demo').toPromise();
expect(tree).toBeTruthy();
expect(tree.exists('/1.log')).toBeTruthy();
expect(tree.readContent('/1.log')).toEqual('111');
});
it('运行外部原理图', async () => {
let runner = new SchematicTestRunner('test', require.resolve('../collection.json'));
let tree = await runner.runExternalSchematicAsync('@angular-devkit/schematics-cli', 'blank', { name: 'unit-name' }).toPromise();
expect(tree).toBeTruthy();
// 这里
tree = await runner.runSchematicAsync('unit-demo', undefined, tree).toPromise();
expect(tree.readContent('/unit-name/package.json')).toEqual(`{"change":true}`);
});
it('运行runner规则', async () => {
let runner = new SchematicTestRunner('test', require.resolve('../collection.json'));
let tree: Tree = await runner.runExternalSchematicAsync('@angular-devkit/schematics-cli', 'blank', { name: 'unit-name' }).toPromise();
// 这里
tree = await runner.callRule(rule1, tree).toPromise();
expect(tree.read('/unit-name/package.json')?.toString()).toEqual(`{"change":true}`);
});
it('单独调用规则', async () => {
let runner = new SchematicTestRunner('test', require.resolve('../collection.json'));
let tree: Tree = await runner.runExternalSchematicAsync('@angular-devkit/schematics-cli', 'blank', { name: 'unit-name' }).toPromise();
let context = runner.engine.createContext(
runner.engine.createSchematic('unit-demo', runner.engine.createCollection(require.resolve('../collection.json')))
);
// 这里
tree = await callRule(rule1, tree, context).toPromise();
});
});
初始化
- 传入集合名(随意),集合路径(绝对)
new SchematicTestRunner('', '');
调用外部原理图
runner.runExternalSchematicAsync('@schematics/angular', 'workspace', {}, this.hostTree);
| 外部集合名 | schematic 名 | 选项 | 树实例 |
|---|---|---|---|
| 可选 | 可选 |
调用内部原理图
- 即初始化 runner 传入的原理图集合中的
runner.runSchematicAsync(schematicName, options, this.tree);
| schematic 名 | 选项 | 树 |
|---|---|---|
| 可选 | 可选 |
创建上下文
let context = runner.engine.createContext(
runner.engine.createSchematic('ng-new', runner.engine.createCollection(require.resolve('../schematics/collection.json')))
);
规则调用
- 直接测试单一规则
callRule(Rule({}), tree, context);
| 规则 | 树 | 上下文 | | —- | — | —— |
- 已有 runner 测试
runner.callRule(rule, tree, parentContext);
| 规则 | 树 | 父级上下文 |
|---|---|---|
| 可选 |
