Manual & Automated Unit Development Testing

Manual and Automated Unit Development Testing

Software and web applications always face bugs during development. Some bugs cause minor issues, while others disrupt daily operations and impact business results. No application avoids bugs entirely. Code changes for new features or fixes often introduce new problems. Modern software includes many connected components, so even skilled developers can miss issues during coding. RSI reduces risk by placing testing at the center of the development process.

How RSI Reduces Software Bugs

Testing stands as the top priority during development. Every code change passes through structured testing stages before reaching the client. Each stage screens for errors and improves usability. This approach protects performance when software goes live. Developers begin testing at the earliest point of development to confirm that new code works as expected. This first layer of quality control uses unit testing.

What Is Unit Testing

Unit testing checks small sections of code to confirm correct behavior. RSI completes unit testing in two forms: manual unit testing and automated unit testing. Each method plays a role in reducing risk and improving software quality.

Manual Unit Testing

Manual unit testing relies on direct code review during execution. Developers use debugging tools to run the program while reviewing logic line by line. This process verifies how data flows through recent code changes. Manual testing demands time and focus. Every update requires a full review to ensure accuracy. While effective, manual testing can slow development if used alone.

Automated Unit Testing

Automated unit testing uses separate test files that isolate individual code segments. These tests run automatically with one action and check specific outcomes. Developers write these tests during development, which often takes as long as writing the code itself. Once complete, automated tests reduce long debugging sessions and help teams move faster with confidence.

Why RSI Uses Automated Unit Testing

Automated unit testing delivers long-term value despite the upfront effort. Developers write tests once and reuse them for future updates. This process allows teams to release changes faster while maintaining stability. Automated tests run consistently and evaluate the same scenarios every time. Consistent testing reduces risk and improves efficiency across the full codebase.
