What is automated testing?
In software testing, test automation is the use of software separate from the software being tested to control the execution of tests and the comparison of actual outcomes with predicted outcomes. Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or perform additional testing that would be difficult to do manually. Test automation is critical for continuous delivery and continuous testing.
Why should I use automated testing?
- Increased Scale – Runs tests 24/7, maximizing efficiency.
- Faster Delivery – Speeds up testing, enabling quicker releases.
- Seamless Releases – Ensures continuous, stable testing during development.
what kinds of tests should be automates?
There are a few factors to consider when deciding whether a test can and should be automated. Here are the most important ones:
- Repeatable:The test must be one that can (and will) be repeated regularly. For instance, there is no point automating a test for a feature that is about to be deprecated.
- Determinant: There has to be a clear right and wrong outcome for the test. In other words, it must be easy for a computer to decide whether the test failed or not.
- Repetitive or tedious: As a rule, humans are very poor at repetitive tasks. Our minds wander or we get distracted. Automation testing is particularly advantageous for any test that involves repeatedly doing the same action, as it ensures consistent and accurate execution.
- Business-Critical:If a test is absolutely critical, you should try your best to automate it and schedule it to run regularly. That way, you can be certain this test is always being carried out.
Test Automation: Faster, Smarter, and More Reliable Software Testing.
Types of Automation Testing:
Automation testing can be particularly beneficial for repetitive tasks, ensuring consistent and reliable results. There are a wide range of types of tests that you can (and should) automate. The following list should help you decide.
Unit Testing – Ensures individual functions work correctly. Automated and runs whenever new code is pushed.
Integration Testing – Verifies that different modules work together. Tests both expected and unexpected inputs.
System Testing – Tests the complete application. Key types include:
- Functional Testing – Checks if the system behaves as expected (e.g., loading user details after login).
- Regression Testing – Ensures new code doesn’t break existing features.
- Smoke Testing – Quickly verifies core functionality after code changes.
Conclusion
Test automation enhances speed, accuracy, and efficiency, allowing teams to run more tests with fewer resources. It ensures faster releases, maintains software quality, and prevents regressions. By automating core testing processes, businesses can streamline development and reduce manual effort. Ultimately, test automation leads to more reliable software and a competitive edge in the market.
