Question

我的排毒测试在本地运行良好，但是每当我从Travis运行它们时，它似乎都失败了。例如，以下在本地运行良好：

test('should have welcome screen and skip button hides on last frame', async() => {
    await expect(element(by.id('WelcomeScreen_Skip'))).toBeVisible();
    await expect(element(by.id('WelcomeScreen_Carousel'))).toBeVisible();
    await element(by.id('WelcomeScreen_Carousel')).swipe('left');
  });

但是，同一代码块在Travis上失败，并出现以下错误：

Welcome Screen › should have welcome screen and skip button hides on last frame

    An assertion failed.
    Exception with Assertion: {
      "Assertion Criteria":  "assertWithMatcher:matcherForSufficientlyVisible(>=0.750000)",
      "Element Matcher":  "((!(kindOfClass('RCTScrollView')) && ((respondsToSelector(accessibilityIdentifier) && accessibilityID('WelcomeScreen_Skip')) && !(kindOfClass('UIAccessibilityTextFieldElement')))) || (((kindOfClass('UIView') || respondsToSelector(accessibilityContainer)) && parentThatMatches(kindOfClass('RCTScrollView'))) && ((kindOfClass('UIView') || respondsToSelector(accessibilityContainer)) && parentThatMatches(((respondsToSelector(accessibilityIdentifier) && accessibilityID('WelcomeScreen_Skip')) && !(kindOfClass('UIAccessibilityTextFieldElement')))))))"
    }


    Error Trace: [

        "Description":  "Assertion with matcher [M] failed: UI element [E] failed to match the following matcher(s): [S]",
        "Description Glossary":    {

        },

        "Line":  "75"
      }
    ]

我注意到了另一种异常行为。当我在await语句的前两行中添加“ waitFor”时，这两行都通过了，但是第三行中的“ swipe”失败了。

test('should have welcome screen and skip button hides on last frame', async() => {
    await waitFor(element(by.id('WelcomeScreen_Skip'))).toBeVisible();
    await waitFor(element(by.id('WelcomeScreen_Carousel'))).toBeVisible();
    await element(by.id('WelcomeScreen_Carousel')).swipe('left');
  });

滑动失败，这没有意义，因为测试表明之前的行中传递了相同的ID。这是错误：

    Exception with Action: {
      "Action Name":  "Swipe Left for duration 0.1",
      "Element Description":  "<RCTCustomScrollView:0x7f967a1e0800; AX=N; AX.frame={{0, 126}, {375, 654}}; AX.activationPoint={187.5, 453}; AX.traits='UIAccessibilityTraitNone'; AX.focused='N'; frame={{0, 0}, {375, 654}}; opaque; alpha=1>",

    }
