Question

如果我从AndroidStudio运行我的Robolectric单元测试，一切都很好，我的所有测试都通过了。如果我尝试从命令行运行它们，“./ gradlew clean test”我得到OutOfMemoryError错误。

我已经尝试在项目的根目录中编辑gradle.properties文件，但这似乎没有任何效果。我甚至将内存限制设置为8g并且仍然存在内存错误，因此我认为文件没有任何影响。

项目 - ＆gt; gradle.properties

我试过answers from other threads但没有成功。当涉及Activity或Fragment时，它似乎只会抛出错误。

欧根是对的。一旦我更新到JDK 8，我的内存不足错误就消失了。

有了这个问题，我留下了一个问题，每个人都面临着从库中运行Robolectric：它没有找到资源。很多人建议复制所有文件。对我来说，就像在gradle中设置src目录一样简单

android {
....
    sourceSets {
    // a work around for robolectric
    // https://github.com/robolectric/robolectric/issues/1796
    test.java.srcDirs += '../App/build/generated/source/r/debug'
}

从gradle运行Robolectric测试会产生OutOfMemoryError。来自AndroidStudio
