测试 (AVD) 测试 - 失败：仪器运行由于 'java.io.IOException' 而失败

Question

当运行使用 Gradle 测试我的 Cucumber-jvm 时出现此错误 Android 模拟器.

完全相同的测试运行在设备上完美，但我需要在模拟器上运行它们才能在 Travis CI

上执行测试

调试错误：

No tests found. This usually means that your test classes are not in the form that your test runner expects (e.g. don't inherit from TestCase or lack @Test annotations).

这是我创建的 CucumberTestCase.class 来配置 Cucumber 将执行哪些测试以及使用 @CucumberOptions:

import cucumber.api.CucumberOptions;

/**
 * This class configures the Cucumber test framework and Java glue code
 */
@CucumberOptions(features = "features", // Test scenarios
        glue = {"com.neoranga55.cleanguitestarchitecture.cucumber.steps"}, // Steps definitions
        format = {"pretty", // Cucumber report formats and location to store them in phone
                "html:/mnt/sdcard/cucumber-reports/html-report",
                "json:/mnt/sdcard/cucumber-reports/cucumber.json",
                "junit:/mnt/sdcard/cucumber-reports/cucumber.xml"
        },
        tags={"~@manual", "@login-scenarios"}
)
public class CucumberTestCase {
}

要启动的命令是：

./gradlew connectedAndroidTest -PdisablePreDex --stacktrace --info

问题'java.io.IOException'是因为Cucumber-jvm在format下无法写入@CucumberOptions中指示的位置.

在我的例子中，这是因为该路径存在于设备上但不存在于模拟器上，这就是它仅在模拟器上失败的原因。

解决办法是把路径改成html、json和junit 向设备和模拟器中可写的路径报告。

我的初始路径 (/mnt/sdcard/cucumber-reports/html-report) 非常适合放置 html 报告并在执行完成后检索它。在设备和模拟器中都有效的路径是下面的例子，但是这个路径将在应用程序被删除后被删除 Gradle 测试执行：

@CucumberOptions(features = "features", // Test scenarios glue = {"com.neoranga55.cleanguitestarchitecture.cucumber.steps"}, // Steps definitions format = {"pretty", // Cucumber report formats and location to store them in phone "html:/data/data/com.neoranga55.cleanguitestarchitecture/cucumber-reports/html-report", "json:/data/data/com.neoranga55.cleanguitestarchitecture/cucumber-reports/cucumber.json", "junit:/data/data/com.neoranga55.cleanguitestarchitecture/cucumber-reports/cucumber.xml" }, tags={"~@manual", "@login-scenarios"} )
