在单元测试中通过Gradle排除罐子 [英] Excluding jars via Gradle in unit tests

问题描述

我要使用 fileTree()包含另一个项目中的一些本地构建的库:

I'm including some locally-built libs from another project by using fileTree():

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    ...
}

对于单元测试，我想使用自己的模拟类而不是这些jar.我如何才能 testImplementation 配置不不使用那些jar文件，而是使用源层次结构之外的类似名称的类?

For unit testing, I want to use my own mock classes instead of those jars. How can I have the testImplementation configure not use those jar files and instead use similarly-named classes out of my source hierarchy?

推荐答案

在我的情况下，我需要包括aar来实现，并用jar替换它以进行单元测试.Gradle 无法排除jar文件，所以我发现了不同之处解决方案.

In my case I needed to include aar for implementation and replace it with jar for unit tests. Gradle can't exclude jar files, so I found different solution.

假设我的文件夹 MyProject 中有一个Android项目.因此，必须有文件 MyProject/build.gradle 和 MyProject/app/build.gradle .我将< my-dependency> .aar 文件和< my-test-dependency> .jar 文件放入 MyProject/app/libs 目录.然后，将该目录作为本地存储库添加到 MyProject/build.gradle 文件中:

Let's say I have Android project in folder MyProject. So there must be files MyProject/build.gradle and MyProject/app/build.gradle. I put <my-dependency>.aar file and <my-test-dependency>.jar files to MyProject/app/libs directory. Then I add this directory as local repository in MyProject/build.gradle file:

allprojects {
    repositories {
        ...
        flatDir {
            dirs 'libs'
        }
    }
}

现在我可以按名称包括和排除我的aar:

Now I can include and exclude my aar by name:

configurations.testImplementation {
    exclude module: '<my-dependency>'
}

dependencies {
    implementation(name: '<my-dependency>', ext:'aar')
    
    testImplementation(name: '<my-test-dependency>', ext:'jar')
    // fileTree also should work, i.e.:
    // testImplementation fileTree(dir: 'libs', include: ['*.jar'])
}
