Could not find method testImplementation() for arguments [junit:junit:4.12]

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

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'android.arch.navigation:navigation-fragment:1.0.0-alpha06'
    implementation 'android.arch.navigation:navigation-ui:1.0.0-alpha06'
    implementation 'android.arch.navigation:navigation-fragment-ktx:1.0.0-alpha06'
    implementation 'android.arch.navigation:navigation-ui-ktx:1.0.0-alpha06'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

This is my build.gradle file and I tried many ways but I can't fix this, when I start Android Studio and gradle starts build the project Android Studio throw this error how can I fix it?( I am new in Android)

Could not find method testImplementation() for arguments [junit:junit:4.12] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

Solution:

In my case well I was getting same error and solution is below.

initially it was

 testCompile 'junit:junit:4.12'

I changed it to

 testimplementation 'junit:junit:4.12'

then it was giving me that error so problem was I needed to use "testImplementation" not "testimplementation".

Final Solution

 testImplementation 'junit:junit:4.12'

Let me know if you still face the same issue.

Thank you!!!

Maybe you forgot to apply jvm-related plug-ins. The most basic is like the following:

apply  plugin: 'java'

or apply other jvm-related plugin

I solved this problem as follows, maybe it will work for you.

before

androidtestImplementation('androidx.test.espresso:espresso-core:3.4.0'

after

testImplementation('androidx.test.espresso:espresso-core:3.4.0'

before

andoidtestImplementation 'junit:junit:4.13.2'

after

testImplementation 'junit:junit:4.13.2'

The error is caused by gradle daemon start with user's locale (TR). Starting gradle daemon with EN locale will solve the problem. In gradle.properties file set user language by updating the following line

org.gradle.jvmargs=-Xmx1536m -Duser.language=en

100% working.

Replace testİmplementation with testImplementation.(İ with I or i)

in your dependencies

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

implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'android.arch.navigation:navigation-fragment:1.0.0-alpha06'
implementation 'android.arch.navigation:navigation-ui:1.0.0-alpha06'
implementation 'android.arch.navigation:navigation-fragment-ktx:1.0.0-alpha06'
implementation 'android.arch.navigation:navigation-ui-ktx:1.0.0-alpha06'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testimplementation 'junit:junit:4.12'
androidTestimplementation 'com.android.support.test:runner:1.0.2'
androidTestimplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

}

Before

I didn't know implementation needs to be within dependencies in build.gradle

// build.gradle
dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
}

implementation 'org.springframework.boot:spring-boot-starter-actuator'

gs-spring-boot/initial [master●] » ./gradlew bootRun

FAILURE: Build failed with an exception.

* Where:
Build file '/home/geoff/work/androidStuff/gs-spring-boot/initial/build.gradle' line: 27

* What went wrong:
A problem occurred evaluating root project 'spring-boot'.
> Could not find method implementation() for arguments [org.springframework.boot:spring-boot-starter-actuator] on root project 'spring-boot' of type org.gradle.api.Project.

Make sure you pay attention to proper Camel Case. TestImplementation not testimplementation. Unless you follow that convention you will receive an error and it will drive you crazy

One of these 3 methods will work

1) Project Structure > Project > and change

Gradle Version: 4.6
Android Plugin Version: 3.2.1

2) change it testImplementation --> testİmplementation

 testİmplementation 'junit:junit:4.12'
    androidTestİmplementation 'com.android.support.test:runner:1.0.2'
    androidTestİmplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

3)

    //testImplementation 'junit:junit:4.12'

    //androidTestImplementation 'androidx.test:runner:1.1.2-alpha02'

    //androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0-alpha02'

Clean --> Rebuild

or

File --> Sync Project with Gradle Files

It is Google's fault.You need to use your countries letters.So use 'İ' instead 'I'.

testİmplementation  'junit:junit:4.12'
androidTestİmplementation  'androidx.test:runner:1.1.1'
androidTestİmplementation  'androidx.test.espresso:espresso-core:3.1.1'

Even though the documentation says

In your app's top-level build.gradle file, specify the following libraries as dependencies:

... I haven't found an example that works that way.

In fact, this GoogleSamples Android Unit Test example specifies:

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

So, move that line to the module build.gradle, not the top-level build.gradle

Can you provide your Gradle version and complete build.gradle ?

Possible issues:

  1. You are missing a plugin definition apply plugin: 'com.android.application'

or any plugin that implicitly uses the Java Plugin ? That's where the testImplementation comes from.

  1. You're using < Gradle 3.x (testImplementation is not available in the previous releases)

Ensure you are using Gradle 3.x+ and that the top level build.gradle has Android Gradle Plugin 3.x+ defined in it : https://developer.android.com/studio/releases/gradle-plugin#updating-plugin

Well, I know that's not the nicest solution for this but this is what worked. I simply commented these lines out:

//testImplementation "junit:junit:4.12"
//testImplementation "org.robolectric:robolectric:3.1.2"

Hope it helps =)
