硒和量角器崩溃，无法截屏

Question

我在 Jasmine 中的每个测试描述都带有一个 afterEach() 来检查测试用例是否通过。如果它没有通过，我想截取有问题的测试屏幕的屏幕截图。

有时我会收到错误的崩溃报告。我不确定如何调试或修复它以了解更多信息。

    afterEach(function() {
        var passed = jasmine.getEnv().currentSpec.results().passed();
        if (!passed) {
            takeScreenCap("FAILEDTESTCASE_" + jasmine.getEnv().currentSpec.description);
        }
    });

崩溃本身

Answer 1

我不会重新发明轮子并使用：

protractor-html-screenshot-reporter（对于 jasmine1）
protractor-jasmine2-screenshot-reporter（对于 jasmine2）

它会为您提供一份不错的 HTML 报告，其中包括屏幕截图。如果您想在失败时进行屏幕截图，请将 use captureOnlyFailedSpecs 设置为 true:

jasmine.getEnv().addReporter(new HtmlScreenshotReporter({
   captureOnlyFailedSpecs: true
}));
