Welcome to the world of automated user interface testing with Stb-tester. In this article, we will guide you through the process of employing Stb-tester to evaluate the user interfaces of set-top boxes and smart TVs. Whether you’re a developer, a tester, or simply curious about the testing process, this guide is designed to provide you with practical insights and actionable steps.
What is Stb-tester?
Stb-tester is a powerful tool that simulates real-user interactions with set-top boxes and smart TVs. By utilizing infrared remote control commands, Stb-tester sends instructions to the device-under-test and evaluates its responses by analyzing video output. Think of it as a meticulous inspector that watches how a TV behaves while you browse through channels or applications.
Getting Started with Stb-tester
Before you begin testing, make sure to have Stb-tester installed and set up on your device. Below are the steps to kick-start your automated testing journey:
- Visit the Stb-tester website to download the necessary files and dependencies.
- Refer to the Getting Started guide for detailed installation instructions.
- Ensure your testing hardware is configured according to the instructions provided in the wiki for optimal performance.
Writing Test Cases
Stb-tester utilizes Python for writing test cases. Below, we will walk through a simple example:
def test_that_i_can_tune_to_bbc_one_from_the_guide():
stbt.press(KEY_EPG)
stbt.wait_for_match(Guide.png)
stbt.press(KEY_OK)
stbt.wait_for_match(BBC One.png)
stbt.wait_for_motion()In this test case, we’re instructing Stb-tester to:
- Press the Electronic Program Guide (EPG) button on the remote.
- Wait for the guide screen to appear, indicated by matching the
Guide.pngscreenshot. - Press the OK button to select BBC One.
- Wait for BBC One to match the associated image,
BBC One.png. - Finally, ensure that the channel is active by waiting for motion.
Think of writing these test cases as programming a robot to navigate through an amusement park. Each command is a step: entering the park, looking for the map, selecting a ride, ensuring it’s in operation, and verifying you’re still moving—this is the essence of how Stb-tester interacts with your devices.
Troubleshooting Common Issues
While setting up or running your tests, you might encounter some stumbling blocks. Here are a few troubleshooting tips:
- Ensure that your device-under-test is connected correctly and powered on.
- If a test case fails to recognize a screen match, check the image references you’re using. Make sure they match the device’s output accurately.
- Ensure you have the necessary permissions and dependencies installed in your Python environment.
