Jasmine 测试失败后执行代码 [英] Execute code after Jasmine test failure

问题描述

只有在 Jasmine 测试失败时才可以做某事吗?与在 it() 之后执行的 afterEach() 并列，无论结果如何，我都在寻找一些仅在 it()<之后执行代码的方法/code> 有一个失败的期望.

Is it possible to do something only if a Jasmine test fails? Juxtaposed with afterEach() which executes after an it() regardless of outcome, I'm looking for some way to execute code only after an it() has a failed expectation.

这个问题不是 Angular 特定的，但在我的场景中，我正在测试一个使用 $log 输出调试消息的 Angular 服务.我不想让我的控制台因测试成功而变得混乱，而只想显示失败测试的附加信息.

This question is not Angular-specific, but in my scenario I am testing an Angular service which outputs debug messages using $log. I don't want to clutter my console for tests that are successful, but only show the additional information for failing tests.

describe("MyService", function() {
    var MyService, $log;

    beforeEach(function() {
        inject(function (_MyService_, _$log_) {
            MyService = _MyService_;
            $log = _$log_;
        });
    });

    afterEach(function () {
        if (/* test failed */) {
            //console.log($log.debug.logs);
        }
    });

    it("should output debug logs when this fails", function() {
        //do something with MyService that would put a message in $log
        expect(false).toBe(true);
    });
});

我正在运行 Jasmine 2.2.0.

这里是一个非常简单的小提琴，它显示了 Jasmine 1.3 jasmine.getEnv().currentSpec 解决方案不再起作用.

here's a very simple fiddle which shows the Jasmine 1.3 jasmine.getEnv().currentSpec solution no longer working.

推荐答案

这是在 Jasmine 2 中重新启用 jasmine.getEnv().currentSpec 的 hack(有点，result 不是完整的 spec 对象，但包含 id、description、fullName、failedExpectations 和 passedExpectations):

Here's a hack to re-enable jasmine.getEnv().currentSpec in Jasmine 2 (sort of, result isn't the full spec object, but contains id, description, fullName, failedExpectations, and passedExpectations):

jasmine.getEnv().addReporter({
    specStarted(result) {
        jasmine.getEnv().currentSpec = result;
    },
    specDone() {
        jasmine.getEnv().currentSpec = null;
    }
});
