Question

我在Jasmine中的每个测试描述都附带一个afterEach()来检查测试用例是否通过。如果它没有通过，我想截取违规测试屏幕的截图。

有时我会收到崩溃报告错误。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）

它会为您提供包含屏幕截图的精美HTML报告。如果您想要针对失败制作屏幕截图，请将captureOnlyFailedSpecs设置为true：

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

硒和量角器崩溃，无法截屏
