Android Studio において、「test は実行できるが androidTest の実行ができない」という症状に陥りました。
今回はその解決方法についてメモしておこうと思います。

環境
- compose_version = '1.0.1' - targetSdk 31 - kotlinCompilerVersion '1.5.21'
今回は環境設定に関する記事なので、以下に gradle ファイルを書き出しておこうと思います。
プロジェクトレベルの build.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

delete rootProject.buildDir

症状
- test は実行できる
- androidTest の実行ができない
- 最初から用意されてるテストすら実行できない
エラーキーワード
- Could not resolve all files for configuration
- app:debugAndroidTestRuntimeClasspath
- Could not resolve junit:junit:4.13.2.
- Cannot find a version of 'junit:junit' that satisfies
the version constraints:
エラーメッセージ
androidTest 実行時のエラーメッセージを抜粋して記述します。
junit:junit:4.13. と junit:junit:4.12. に依存するパッケージがあり、その読み込みの衝突が起こった結果、どちらも読み込めてないのかな、と思いました。
4: Task failed with an exception.

解決策
build.gralde の中に、次のような設定（configurations）を記述します。
依存関係の衝突がが起きた時に、無理矢理使うバージョンを指定するためのものだと理解しています。（新しいものの方がいいだろう、というノリで 4.13.2 の方を選択しました。）
android {
packagingOptions {
...
}
configurations.all {
resolutionStrategy {
force 'junit:junit:4.13.2'
}
}
}

おわりに
今回は androidTest を走らせようとした際に起こった、依存性の衝突の回避方法について紹介しました。
gradle の部分は毎回コピペで済ませてしまっているのでいつか理解したいと思います。
