Top 10 Test Automation Tools

Developer Testing is an Important Step towards Accountability. It gives Developers a way to Demonstrate the Quality of the Software they Produce. – Kent Beck (American Software Engineer and Creator of Extreme Programming)

Software Testing is crucial for assessing the quality, reliability and performance of a product. It is an indispensable phase of a software development lifecycle. While testing can be undertaken in different ways, the shortcomings of Manual Testing have only increased the demand for Automation Testing.

Conducting tests in an automated fashion requires the employment of Automation Testing Tools which help in facilitating this process.

In this blog, we will look at some of the best Test Automation Tools which would help you to execute test cases. However, before we begin with the Automation Tools List, let us look at some of the general questions surrounding Automation Testing.

What is Test Automation?

Automation Testing is a technique in software testing which makes use of Automation Testing Tools for executing a test case suite. The process is so designed that it feeds data into the system and compares the actual outcome with the expected result, followed by generating a detailed test report.

The objective of Test Automation is to lessen the number of test cases which are required to be executed manually and not necessarily to be a replacement for Manual Testing.

Regression Tests which are essentially repetitive in nature are usually automated. Similarly, another form of Automation Testing is data driven testing, which involves using a set of test data to drive the automated test scripts. This allows testers to test multiple scenarios quickly and thoroughly, using a single test script.

What is Test Automation

What are Automation Tools?

Software Testing cannot be carried out without the appropriate test automation tools. On much the same note, Automated Testing is only possible through the right Automation Testing Tools.

These automated software testing tools are important determinants of whether the advantages of automation would be delivered and how automation will be executed in the first place. These Automated Testing Tools are an integral component of the DevOps toolchain.

Development cycles which run in a successive manner, involves the execution of the same test suite in a repeated manner. An Automation Tool can help in recording this test-suite and re-playing it as and when required. Automation of the test suite removes the need for human intervention.

There are three major categories of Software Testing Tools used in Automation Testing:

  • Open Source Test Automation Tools: Published source code, can be freely used by anyone
  • Commercial Automation Testing Tools: Larger support, cost more money
  • Custom Test Automation Tools: Made for specific projects
