Automated regression testing is the process of using test scripts to validate that newer versions of software code have not introduced problems with older versions. It is a best practice for ensuring continued interoperability between components for each software release.
Regression testing is the testing of software modules from previous versions of a program in an attempt to discover new bugs created by the software developer. Automated regression testing refers to the process by which computer software is tested in an automated manner using test scripts. This type of regression testing is a process in which test scripts are run against software code to validate that newer versions of the code have not introduced problems with older versions.
Software development is the art of writing software code to complete a task in an automated way, which typically increases productivity for individuals or organizations. The software development process includes a lifecycle that requires significant testing before making the software available for public consumption. This test can get tedious and repetitive when done manually, which is why automated regression testing was created.
Testing is a critical function for all software development as it is designed to ensure that the software application meets the customers’ needs. Software application testing includes four main areas, namely unit testing, integration testing, functional testing, and performance testing. Automated regression testing is the process by which previous tests for these test areas are reviewed for completeness.
Testing any software component requires the creation of test scripts. Test scripts are instructions for completing a test, including requirements for the inputs and outputs of a test case. Each test case is placed in a test script to create a complete test of an application.
Test scripts can be automated by writing code that will execute the statements within a test case. This automation isn’t necessary for testing an application, but it’s a best practice, as it increases productivity and reduces the risk of human error during testing. Automated regression testing is the process of running previous automated test scripts to ensure that any new code hasn’t introduced errors that were previously tested and avoided.
Software can be thought of as a complex set of modules that rely on the complete cooperation of functions independent of both the hardware and software of a computer. It is imperative that each iteration of the software code is fully tested to ensure that the collaboration between these modules remains intact. Automated regression testing is a best practice process for ensuring continued interoperability between components for each software release.
