Testcafe-在运行所有夹具后如何运行代码 [英] Testcafe - How to run code after all the fixtures are run

问题描述

我想创建SQL Server数据库的快照，然后在所有固定装置"运行之后将其还原.

I want to create a snapshot of the SQL server DB and then restore it after "all the fixtures" are run.

我可以在每个固定装置之后通过钩住固定装置后进行操作.但是，这在运行测试时会引起问题，因为还原后数据库可能仍处于过渡状态.所以我宁愿在所有固定装置之后做.

I can do it after every fixture through .after hook in a fixture. However, that is causing issues while running tests since the DB may be still in transition after a restore. So I would prefer to do it after all the fixtures.

推荐答案

您还可以使用TestCafe Runner类返回Promise对象.完成所有测试/固定后，您可以使用此对象运行自定义清理代码.

You can also use the TestCafe Programming Interface API. The TestCafe Runner class returns a Promise object. You can use this object to run your custom cleanup code after all tests/fixtures are completed.

这是一个例子:

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

createTestCafe('localhost', 1337, 1338)
    .then(tc => {
        testcafe     = tc;
        const runner = testcafe.createRunner();

        return runner
            .src(['tests/fixture1.js', 'tests/fixture2.js', 'tests/fixture3.js'])
            .browsers(['chrome', 'safari'])
            .run();
    })
    .then(failedCount => {
        // Clean up your database here...
        testcafe.close();
    });
