无论测试失败，Mocha中的挂钩都会运行吗？

Question

就像标题所说的那样。即使测试失败，Mocha中的before / after / beforeEach / afterEach挂钩也能正常工作吗？

Answer 1

是的，即使测试失败，它们也会运行。 但是，如果使用bail选项运行Mocha，则拆卸挂钩将不会运行。

这里只是对现有的测试套件进行了快速检查 代码：

setup(function() {
    console.log("1");
});
teardown(function() {
    console.log("2");
});

执行：

D:\Dev\JS\toposort>mocha


  Toposort
    ◦ should sort correctly: 1
    √ should sort correctly
2
    ◦ should find cyclic dependencies: 1
    1) should find cyclic dependencies
2
    ◦ #2 - should add the item if an empty array of dependencies is passed: 1
    √ #2 - should add the item if an empty array of dependencies is passed
2


  2 passing (15 ms)
  1 failing

  1) Toposort should find cyclic dependencies:
     AssertionError: expected [Function] to not throw 'Error' but [Error: Cyclic dependency found. '3' is dependent of itself
.] was thrown

D:\Dev\JS\toposort>mocha --bail
