如何针对特定的Gradle构建风格从命令行运行单个单元测试方法

问题描述

我试图从命令行运行一个Android测试用例.

I am trying to run just a single Android test case from the command line.

在IDE中，我可以右键单击并运行，但是在CLI中，以下操作将失败:

From the IDE I can just right click and run, but from CLI with the following it fails:

./gradlew test --tests "com.xyz.b.module.TestClass.testToRun"

错误:

> Unknown command-line option '--tests'.

如何运行单个UNIT TEST方法?我想强调的是，我想运行单个单元测试，而不是从命令行运行仪表测试.

How can I run a single UNIT TEST method? I want to emphasis that I want to run a single unit test, not an instrumentation test from command line.

更新:我有一个摄像头应用.想象一下，我有一个名为usCameraDebug的构建变体. (这意味着美国相机调试)现在您能告诉我如何运行一个称为mySingleTest的测试用例吗?

Update: I have a camera app. Imagine that I have a build variant called usCameraDebug. (That means united states camera debug) Now can you tell me how to run a single test case i called mySingleTest?

正如您提到的，我尝试过此操作:./gradlew test --tests "*mySingleTest"

I tried this as you mentioned: ./gradlew test --tests "*mySingleTest"

和./gradlew app:usCameraDebug test --tests "*mySingleTest"

，还有:./gradlew app:usCameraDebugUnitTest --tests "*mySingleTest" 但它 .不起作用.凯恩，您告诉我要根据我的构建变型确切输入什么.默认情况下，其位于名为"app"的模块中.

and also: ./gradlew app:usCameraDebugUnitTest --tests "*mySingleTest" but it . does not work. caan you tell me exactly what to type based on my build variant. its in a module called "app" as defaulted.

这是我要运行的测试:

package  com.xyz.cameras.parts
    @Test
        fun mySingleTest(){
            assertEquals(12,13)
        }

推荐答案

在查找测试名称时，您需要在模式中指定一个通配符，并确保使用模块+样式. --tests不适用于./gradlew test或./gradlew check

You need to specify a wildcard in the pattern while looking for the test name, and make sure to use module + flavor. --tests will not work with ./gradlew test or ./gradlew check

尝试此模式-> ./gradlew :<module>:<flavor> --tests "*textThatTestNameContains*"

示例->./gradlew :profile:testDebug --tests "*my_profile*"将运行此测试:

Example ->./gradlew :profile:testDebug --tests "*my_profile*" will run this test:

@Test
public void my_profile_pageview()

此外，使用--info标志运行有助于查看测试本身或--debug以获得更多输出.例如./gradlew --info :profile:testDebug --tests "*my_profile*"

Additionally, running with --info flag helps to see the tests themselves or --debug for more output. e.g../gradlew --info :profile:testDebug --tests "*my_profile*"
