Testing Android applications requires a deep understanding of various tools and commands. Among the most powerful of these tools are Android Debug Bridge (ADB) commands. ADB commands offer developers a comprehensive set of actions to perform various tasks such as installing applications, debugging, accessing device shell, etc. In this article, we will delve into the world of ADB commands, highlighting the essential ones for Android testing. We’ll explore their functions, how to use them, and how they can help streamline your testing process for Android applications. Whether you’re a seasoned Android developer or just starting out, this guide will equip you with the knowledge you need to make your testing more efficient and effective.

What are the adb commands used in testing?
Android Debug Bridge (adb) is a versatile command-line tool that lets you communicate with a device. It is a client-server program that includes three components: a client, a daemon, and a server. Adb commands are essential for Android testing as it allows developers to communicate with devices to install and debug their apps.
Here are some of the commonly used adb commands in testing:
- adb devices: This command lists all connected devices.
- adb install: This command is used to install an APK file on the device.
- adb uninstall: This command is used to uninstall an application from the device.
- adb push: This command pushes a file onto the device.
- adb pull: This command pulls a file from the device.
- adb logcat: This command displays the log data onto the screen.
- adb shell: This command launches a shell on the device.
- adb bugreport: This command generates a bug report.
- adb get-state: It prints the current state of the device (device, recovery, sideload, etc.).
- adb reboot: This command is used to reboot the device.
- adb reboot-bootloader: It reboots the device into the bootloader.
- adb start-server: This command starts the adb server.
- adb kill-server: This command stops the adb server.
These are just a few examples of the many commands available in adb that can be used in the process of testing and debugging Android applications.
How to run adb Android test?
Android Debug Bridge (adb) is a versatile command-line tool that lets you communicate with a device. It facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that you can use to run a variety of commands on a device.
To run an adb Android test, follow the steps below:
Connect your Android device to your computer. You can do this via USB or wirelessly.
- Open the terminal on your computer.
- Navigate to the directory where your Android project is located using the ‘cd’ command.
- Make sure your device is properly connected by typing ‘adb devices’. This command should return a list of connected devices.
- Before running the tests, you need to install the app on the device. You can do this with the command ‘adb install path_to_your_apk’. Replace ‘path_to_your_apk’ with the path to your .apk file.
Now you can run your test using the ‘adb shell’ command followed by ‘am instrument’. The full command would be ‘adb shell am instrument -w package_name/test_runner’. Replace ‘package_name’ with the name of your package and ‘test_runner’ with the name of your test runner.
The test results will be displayed in the terminal.
It’s important to note that you need to have Android SDK and adb installed on your computer to run these commands. Also, developer options and USB debugging need to be enabled on your Android device.
How to use adb commands in Android?
ADB, or Android Debug Bridge, is a versatile command-line tool that lets you communicate with a device. It facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that you can use to run a variety of commands on a device.
To use ADB commands in Android, follow these steps:
- Download and Install Android SDK Platform Tools: These tools include adb and can be downloaded from the Android developer site.
- Enable USB Debugging on Your Phone: Go to Settings > About Phone > tap on ‘Build Number’ 7 times until Developer Mode is enabled. Then, go back to settings > Developer Options > Enable USB Debugging.
- Connect Your Phone to Computer: Use a USB cable to connect your Android device to your computer.
- Open Command Prompt: Navigate to the folder where you installed ADB (usually it’s C:adb). Open a command prompt in the same directory as your adb and fastboot executables. (To do this hold Shift and right click within the folder then select ‘Open command window here’).
Here are some basic ADB commands:
- adb devices: This command will list the devices connected to your computer.
- adb install : This command installs an apk file to your phone.
- adb uninstall : This command uninstalls an app from your device.
- adb push: This command moves a file from your computer to your device.
- adb pull: This command moves a file from your device to your computer
- adb logcat: This command lets you view the device log in real-time.
Remember, using adb commands requires a fair bit of technical knowledge, so be sure to understand what each command does before you use it. Always use caution when working with system-level commands, as incorrect usage can result in unintended consequences.
How do I run adb commands?
ADB, or Android Debug Bridge, is a versatile tool that allows you to manage the state of an emulator instance or Android-powered device.
Here are the steps to run ADB commands:
- First, you need to connect your Android device to your computer. This can be done using a USB cable.
- Before you can start using ADB commands, you need to enable USB debugging on your device. You can do this by going to ‘Settings’ > ‘About phone’ > ‘Build number’. Tap on the build number seven times to unlock developer options. Go back to ‘Settings’ > ‘Developer options’ and enable ‘USB debugging’.
- Next, you need to install ADB on your computer. The easiest way to do this is through the Android SDK, which can be downloaded from the Android Developer website.
- After installing the Android SDK, navigate to the platform-tools directory. This is where the ADB program is stored.
- Open a command prompt in the same directory as ADB. This can be done by holding Shift and right-clicking in the platform-tools folder, then selecting ‘Open command window here’.
- To ensure your device is properly connected, you can run the command ‘adb devices’. This should return a device ID. If it doesn’t, make sure your device is properly connected and USB debugging is enabled.
- Now you can execute ADB commands. These commands are executed in the command prompt, and the syntax is ‘adb [command]’. For example, to install an app, you would use the command ‘adb install [path_to_apk]’.
Remember to replace ‘[command]’ and ‘[path_to_apk]’ with the actual command and path to the APK file you want to install. ADB commands allow you to do many things, such as install apps, debug apps, access device logs, and much more.
ADB apps
ADB (Android Debug Bridge) apps are applications that allow for communication between an Android device and a personal computer. ADB allows developers to debug their apps, run commands, and perform other technical tasks directly on the Android device from the computer.
ADB apps can be used to install or uninstall apps, copy files, run shell commands, and more. Some commonly used ADB apps include ADB Shell, ADB Push, and ADB Pull. It’s a versatile tool that’s essential for Android developers, but can also be used by advanced users looking to modify or tweak their Android devices. It should be used with caution, however, as incorrect use can lead to data loss or other issues.
In conclusion, ADB commands are a powerful tool for testing Android devices. They allow developers to directly communicate with the device, debug applications, install or uninstall apps, copy files, access logs, and much more. These commands provide a detailed and in-depth understanding of how an application operates on an Android device.
Whether you are a seasoned developer or a novice tester, understanding and utilizing ADB commands in your testing process can greatly streamline your workflow and enhance your testing capabilities. So, take some time to familiarize yourself with these commands and harness the power of ADB for more efficient and effective Android testing.
