Test selection algorithms: The role of the Test Advisor Score

Software testing is critical for creating high-quality, reliable applications. However, optimizing testing time and cost is a growing challenge, especially in agile development. This is where test selection algorithms help. They intelligently choose the most important tests and reduce unnecessary runs. One such solution is the Test Advisor Score, the intelligent scoring system of TestNavigator. Its goal is to help you prioritize test cases more effectively.

One such solution is the Test Advisor Score, the intelligent scoring system of TestNavigator. Its goal is to help you prioritize test cases more effectively.

The Role of Test Selection Algorithms

Modern software development faces a big challenge: fast and efficient testing. Systems are becoming more complex, and after every update or change, we need to check if the new code has broken anything. The problem? A large application might have thousands of tests, and running all of them is time-consuming and expensive.

Test selection algorithms offer a solution. Their main purpose is to run only the tests needed after a given update. This speeds up feedback and lowers testing costs.

A test selection algorithm uses a method that selects the tests necessary to validate the functionalities affected by code changes. Why do we need this?

  1. We do not always need to run all tests.
  2. Not all tests are equally important.
  3. Effective selection saves time and money.
  4. One innovative approach is the TestNavigator Test Advisor Score system. Let’s see how it works in practice!

How the TestNavigator Test Selection Algorithm Works

Test Advisor Score is the intelligent scoring system inside TestNavigator. It helps you rank your test cases efficiently. First, it analyzes code changes between software versions and identifies areas with a higher risk of failure. Test cases related to these modified parts get a higher priority score because these changes pose the greatest risk.

The algorithm also considers code complexity. Test cases covering more complex or hard-to-manage features receive higher scores. This way, not only are risky changes tested, but also complex parts of the code that are more prone to errors.

Each test case gets a score from 0 to 10. A higher score means higher execution priority. By focusing on both changes and code complexity, the Test Advisor Score helps optimize the testing process and improve software quality.

A Practical Example: How TestNavigator Assists Testing

Imagine an e-commerce website introducing a new payment feature. In a traditional regression testing process, you might run all related tests—even those not directly impacted by the change.

TestNavigator first analyzes the changes and filters out tests that are clearly not affected. Then, based on code complexity and the modified areas, it assigns a score to the most critical features (for example, transaction processing and authentication). After that, testers only need to run the test cases for these high-priority areas, which saves significant time and cost.

In a pilot project with a local financial company, data showed that only 30% of the original tests were needed for regression. Additionally, one of the prioritized tests failed during execution, revealing a real issue.

Intelligent Test Selection Is the Future

Test selection algorithms bring a new perspective to software testing. The TestNavigator algorithm that generates the Test Advisor Score is an innovation that helps companies test faster, more efficiently, and at lower cost.
