android - 尝试使用 proguard 运行测试

Question

我正在尝试在启用了 proguard 的 apk 上运行单元测试。

这是我的 build.gradle:

  buildTypes {

        debug {
            debuggable true
            minifyEnabled true
            ext.alwaysUpdateBuildId = false

            testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-test-rules.pro'
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }

...
}

和我的 proguard-test-rules.pro

# Proguard rules that are applied to your test apk/code.
-ignorewarnings

-keepattributes *Annotation*

-dontnote junit.framework.**
-dontnote junit.runner.**

-keep androidx.test.**
-keep org.junit.**
-keep org.hamcrest.**
-keep com.nhaarman.mockitokotlin2.**
-keep androidx.arch.core.**
-keep com.android.support.test.uiautomator.**
-dontwarn androidx.test.**
-dontwarn android.test.**
-dontwarn org.junit.**
-dontwarn org.hamcrest.**
-dontwarn com.squareup.javawriter.JavaWriter
# Uncomment this if you use Mockito
-dontwarn org.mockito.**

-kepp com.google.truth.**

-keep class com.fireblocks.**
-keep @org.junit.runner.RunWith public class *

-keep class androidx.test.internal.runner.listener.InstrumentationRunListener
-dontwarn org.junit.runner.**
-keep class org.junit.runner.notification.RunListener

我的测试因以下异常而无法启动:

我如何解决它？

Answer 1

似乎 testProguardFiles 被完全忽略了。
我不得不将一些规则移动到普通的 proguard 文件中，以便能够保留运行测试框架的代码。
不是最佳的，但现在可以了。
