[英]Does after block still excecute if before or it block fail in mocha test
If a mocha test looks like this如果 mocha 测试看起来像这样
describe("create a user") {
before("login to system") {}
it("execute assertion") {}
after("delete the user") {}
}
If either before or it block failed, does the after block still execute or no?如果 before 或 it 块失败,after 块是否仍然执行或不执行?
Yes, when test fails it will run after
hook.是的,当测试失败时,它会after
钩子after
运行。
This code:这段代码:
before("login to system", () => {
console.log("BEFORE")
throw new Error('error');
})
it('testing...', (done) => {
console.log("IT")
done();
});
after("delete the user", () => {
console.log("AFTER")
})
Output this:输出这个:
BEFORE
1) "before all" hook: login to system for "testing..."
AFTER
0 passing (14ms)
1 failing
1) States Get
"before all" hook: login to system for "testing...":
Error: error

Also you can check this github discussion: #1612 where here says:你也可以查看这个 github 讨论: #1612 , 这里说:
Please see the example below, showing that after is correctly invoked after the beforeEach failure请看下面的例子,显示after在beforeEach失败后被正确调用
The code编码
// example.js
before(function() {
console.log('before');
});
after(function() {
console.log('after');
});
describe('suite', function() {
beforeEach(function() {
throw new Error('In beforeEach');
});
afterEach(function() {
console.log('afterEach');
});
it('test', function() {
// example
});
});
And the output.和输出。
// Test run
$ mocha example.js
before
․afterEach
after
0 passing (7ms)
1 failing
1) suite "before each" hook:
Error: In beforeEach
