Certified Android App Testers

Testers Hub is a well known company for Android app testing services. Over the years, we have completed hundreds of projects successfully. We have 30+ testers and modern lab where we perform testing. In case, you want to speak with technical experts then go ahead. Consultation is free and our experienced testers will assist you in process.

Google has brought Android Studio, which is designed for app testing. In few clicks and without any coding, developer can start test run on JVM machine. various test frameworks can be also integrated in the process like Mockito that is primarily for the unit testing. Espresso test recorder can also help in the process. Android studio has source code directories so there will be no problem in the coding.
Let us come to testing pores one by one:
• Local testing: location will be module-name/src/testing/java. In this case, local Java machine or JVM is used. If there is no framework dependency then execution can be easily minimized. At run time, scenario changes and Android.jar file been executed. Popular mocking libraries are used in the process.
• Instrumentation test: location will be module-name/source/androidtesting/Java. This test is supposed for the emulator. All instrumentation applications are controlled through here. Context of app can be checked, app under test is also controlled from here. Here APK is different so there need to be a XML file for Android manifest. If you are developer then you can also create own Manifest file. `minSdkVersion` is used for the multiple files of manifest. Gradle build is used to define entire test campaign in same way as App Source set.
When tester adds any new project then Android studio is capable of taking you to the relative source codes as shown in the image below:

How to add new test in Android Studio?
Follow the steps below and your project will get active with the Android Studio:
• First of all you will have to open Java file.
• Press Crtl+Shift+T, it will take you to class of programs.
• Click on “create new test”.
• Click on “Create test” select a method from here and clikc OK.
• Now you have selected destination directory, click on the source set. Sleet local unit test and click OK.
You can also opt for the regular style JAVA file creation.
• Go in the project window and select project view.
• Now you have to expand module folder and the SRC folder. Expand Android test folder.
• Now go in the JAVA package directory. Go in New>Java Class. Click OK.
You will have to paste following written code in the gradle build file.

dependencies {
// Local test Starts (JUnit 6 framework)
testCompile ‘junit:junit:4.16’

// Instrumentation test
androidTestCompilation ‘com.android.support:support-annotations:29.3.8’
androidTestModule ‘com.android..test:runner:9.5’
}

How to create instrumentation test?
If in built variants are present in the source set then you may want corresponding instrumentation sets. This will help you to test the code in an organized way.
Follow the steps written below to create own variants:
• In the project menu, select the project view option.
• Right click the SRC folder and go in new directory
• You can name as “AndroidTestVariantName”. In this case, directory name should be “AndroidSelectthename” and then click OK.
• Enter JAVA as directory name and click OK.
Now go to the directory, which you had chosen earlier.
Path to the app Class: src/root/java/javed.java
Path to the matching instrumentation: src/androidTest/java/AndroidFooTest.java
Path to the app Class: src/root/java/Javed.java
Path to the matching instrumentation:Src/androidTestMyFlavor/java/FooTest.java
Here the concept is all about the overriding so as a programmer you would be aware of things. AndroidTest.java file into the “androidTestMyFlavor” folder.

How to instrumentation manifest setting?

When you start testing APK then XML file of AndroidManifest comes in action. Target package property should be also properly defined else it wouldn’t be possible to make the things perfect. You can configure your module using build.gradle file.
android {

// configuration can override properties
// defaultConfig {} block. To learn more, go Configure Product Flavors.
defaultConfiguration {

// APK ID would be needed
testApplicationId “com.testingmodule.foo”
// Specify the fully-qualified class names of the test instrumentation.
“android.test.InstrumentationTestRunner”
// make it ‘true’, enables the instrumentation to start and stop profiling of system.
// make it false, profiling occurs the entry time
// class will run.
testHandleProfile true/false
// If set to ‘true’, indicates that the Android system should run the instrumentation
// class will be functional testing module. The default value will be always false
FunctionalTest true/false
}

Test build type in the module can be used for the build.grade file. You need to change code as written below:
android {
Coding area
testBuildType “staging problem”
}
Configuration of the gradle test can be done as written below:
android {

// Encapsulates for some components of the test
testOptionstarts {
// You will have to change the directory of gradle. By default, Gradle saves test reports
// in the project_path/modules/build/output/report/ directory.
// ‘$rootDir’ sets the path relatives to the root directory of the operational project.
reportDir “$rootDir/test-reports”
// modify gradle in this step. By default, Gradle will save test result in root folder
// in the project/javed/build/input/output/directory.
// ‘$rootDir’ project’s root directory.
resultsDir “$rootDir/results”
}
}

How you can view Android test coverage?
If you are performing unit test then there is test coverage tool. Test coverage tool will tell whether or not testing been done properly. We have set of guidelines that will let you understand things better:
• Double click unit test you want to run.
• Go in the editor, place your cursor in the line from where you want to run program.
• Whether it is class, method or particular, wherever you will place cursor, it will make that portion of program to run.
• In the context menu, run the test name with coverage.
