我有一个flaky end-to-end test,它使用Detox和Mocha。
Mocha测试运行程序允许使用multiple retries。我尝试使用推荐的Mocha语法:
// auth.spec.js
describe('App authentication', () => {
this.retries(2);
it('should have a login screen', async () => {
await expect(element(by.id('LoginScreenView'))).toBeVisible();
});
});
但是,当以Mocha作为测试运行程序运行Detox时,this
是一个空对象({}
),并且没有retries
函数。
它会产生以下错误:
node_modules/.bin/mocha __e2e__ --opts __e2e__/config/mocha.opts --
configuration ios.sim.debug --grep :android: --invert --artifacts-location "__e2e__/artifacts/ios.sim.debug.2018-10-17 22-51-12Z"
/<path>/__e2e__/auth.spec.js:10
this.retries(2);
^

有没有办法自动重试排毒失败的测试?
答案 0 :(得分:1)
this
无法使用箭头功能,因此必须将其更改为普通的
// auth.spec.js
describe('App authentication', function () { // change it
this.retries(2);
不建议在Mocha中使用最佳做法
