QA for Skype Click to Call Web Browser Functionality

Challenge

Before Skype Click to Call, users had to manually dial phone numbers they found on web pages, which was time-consuming and resulted in many wrong-number calls. The plugin made it easier by allowing users to click phone numbers directly on a web page to make calls. However, some bugs needed to be addressed. 

Our team was tasked with thoroughly testing the plugin across multiple browsers to ensure it worked consistently. We faced challenges like ensuring phone numbers were detected correctly, calls were initiated smoothly, and the plugin didn’t slow down or crash the browser. We also had to ensure it worked well with different web page layouts and in various languages.

Solutions

Our comprehensive testing strategy involved four key approaches:

Manual testing. We explored the plugin’s functionality, simulating real-world user scenarios. This included testing various web layouts, phone number formats, and edge cases to ensure a smooth user experience.

Black-box testing. We verified the plugin’s inputs and outputs without access to the internal code. This involved testing phone number recognition accuracy, call initiation speed, and proper integration with the Skype application.

Regression testing. After each update, we re-ran our test suite to catch any new bugs or unintended side effects. This iterative process helped maintain plugin stability throughout development.

Localization testing. We checked the plugin’s functionality across multiple languages and regions, ensuring proper number formatting, currency symbol placement, and compatibility with international phone numbers.

Results

Our testing efforts made a significant difference in improving the Skype Click to Call plugin’s performance. After identifying and fixing bugs, the plugin became stable across multiple browsers. It could now detect phone numbers reliably, initiate calls without delays, and work smoothly without affecting browser performance. Localization testing ensured the plugin worked well in different languages and regions, giving users a consistent experience no matter where they were.
