Download (junit-4.12.jar) from https://github.com/junit-team/junit4/wiki/Download-and-Install and copy it in your libs folder:(yourProjectFolder/app/libs)

and then in build.gradle(Module: app) use this codes:

dependencies {
...
compile files('libs/junit-4.12.jar')
...
}

then rebuild your project.
