2 testcafe runner 與 promise.race 但如何一起運行這些？

Question

我在 testcafe 中有 2 個 runner.js，我想一起運行這 2 個 runner，我應該怎么做？

runner1.js

const createTestCafe = require('testcafe');
let testcafe = null;

createTestCafe()
.then(tc => {
    testcafe     = tc;
    const runner = testcafe.createRunner();

    let id;
    const deadlinePromise = new Promise((resolve,reject) => {
        id=setTimeout(() => {
       clearTimeout(id);
       reject('testcase couldnt meet the actual preferred time');
        },215000)
     });

const runPromise=runner
    .src(test1.ts)  
    .browsers('chrome:headless')
    .reporter('html-testrail')
    .run({skipJsErrors:true})             


race =Promise.race([runPromise,deadlinePromise])
race.then((res) => console.log(res))      

})

       .catch(failedCount => {
           console.log('Tests1 failed: ' + failedCount);
            testcafe.close();
        })

runner2.js -- 類似但不同的src和deadlinePromise中的不同時間

 const createTestCafe = require('testcafe');
  let testcafe = null;

createTestCafe()
.then(tc => {
    testcafe     = tc;
    const runner = testcafe.createRunner();

    let id;
    const deadlinePromise = new Promise((resolve,reject) => {
        id=setTimeout(() => {
       clearTimeout(id);
       reject('testcase couldnt meet the actual preferred time');
        },150000)
     });

const runPromise=runner
    .src(test2.ts)  
    .browsers('chrome:headless')
    .reporter('html-testrail')
    .run({skipJsErrors:true})             


race =Promise.race([runPromise,deadlinePromise])
race.then((res) => console.log(res))      

})

       .catch(failedCount => {
           console.log('Tests1 failed: ' + failedCount);
            testcafe.close();
        }) 

所以基本上兩個跑步者都包含 promise.race。 現在我想從命令行或另一個跑步者一起運行這兩個跑步者。 我怎么做？

Answer 1

我看到您已經在 testcafe 的主跑步者中為其他幾個跑步者提出了類似的問題？ 線程，所以請不要重復問題。

我准備了一個演示所需行為的示例。 請參閱以下代碼：

const createTestCafe = require('testcafe');

(async () => {
    const testCafe = await createTestCafe();

    let timeout1, timeout2;

    const runner1RunPromise = testCafe
        .createRunner()
        .src('test1.js')
        .reporter([{ name: 'spec', output: 'report1.txt' }])
        .browsers('chrome')
        .run();

    const deadline1Promise = new Promise((resolve, reject) => {
        timeout1 = setTimeout(() => {
            runner1RunPromise.cancel();

            console.log('runner 1 canceled');

            resolve();
        }, 5000);
    });


    const runner2RunPromise = testCafe
        .createRunner()
        .src('test2.js')
        .reporter([{ name: 'spec', output: 'report2.txt' }])
        .browsers('firefox')
        .run();

    const deadline2Promise = new Promise((resolve, reject) => {
        timeout2 = setTimeout(() => {
            runner2RunPromise.cancel();

            console.log('runner 2 canceled');

            resolve();
        }, 40000);
    });

    const race1 = Promise.race([runner1RunPromise.then(() => clearTimeout(timeout1)), deadline1Promise]).then(() => { console.log('race 1 finished') });
    const race2 = Promise.race([runner2RunPromise.then(() => clearTimeout(timeout2)), deadline2Promise]).then(() => { console.log('race 2 finished') });

    await Promise.all([race1, race2]);

    console.log('finished');

    await testCafe.close();
})();

請注意，您不需要創建多個 testcafe 實例。 創建幾個跑步者就足夠了。 請參閱以下描述如何取消正在運行的任務的文章： https://devexpress.github.io/testcafe/documentation/using-testcafe/programming-interface/runner.html#cancelling-test-tasks

因此，您可以在超時時取消測試執行或等待所有測試完成。
