firebase testlab xctest成功，但没有屏幕截图

Question

我通过firebase testlab运行了xctest（UI测试），它已经成功了，但

在情况下没有屏幕截图，我通过“ xctattachment”进行附件，

- (void)testHomeButton {
    XCUIApplication *app = [[XCUIApplication alloc] init];
    [app launch];
    
    // click button2
    XCUIElement *button2 = app.buttons[@"button2"];
    [button2 tap];
    
    // get button2 screenshoot
    XCTAttachment *attachment1 = [XCTAttachment attachmentWithScreenshot:XCUIScreen.mainScreen.screenshot];
    attachment1.name = @"button2 Screen";
    attachment1.lifetime = XCTAttachmentLifetimeKeepAlways;
    [self addAttachment:attachment1];
    
    // click button3
    XCUIElement *button3 = app.buttons[@"button3"];
    [button3 tap];
    
    // get button3 screenshoot
    XCTAttachment *attachment2 = [XCTAttachment attachmentWithScreenshot:XCUIScreen.mainScreen.screenshot];
    attachment2.name = @"button3 Screen";
    attachment2.lifetime = XCTAttachmentLifetimeKeepAlways;
    [self addAttachment:attachment2];
    
    // click testview
    XCUIElement *testview = [app.otherElements.element childrenMatchingType:XCUIElementTypeAny][@"testvc_view"];
    [testview tap];
}

我通过Xcode Test（命令 + U）成功地进行了屏幕检查。 xcode测试结果

但是，firebase的测试结果没有屏幕截图，只包含日志和视频

。我应该做屏幕截图吗？

非常感谢！
