AUTOMATION TESTING means using an automation tool to execute your test case suite. On the contrary, Manual Testing is performed by a human sitting in front of a computer carefully executing the test steps.
The automation software can also enter test data into the System Under Test, compare expected and actual results and generate detailed test reports. Test Automation demands considerable investments of money and resources.
Successive development cycles will require execution of same test suite repeatedly. Using a test automation tool, it's possible to record this test suite and re-play it as required. Once the test suite is automated, no human intervention is required. This improved ROI of Test Automation. The goal of Automation is to reduce the number of test cases to be run manually and not to eliminate Manual Testing altogether.
Automated software testing is important due to the following reasons:
Test cases to be automated can be selected using the following criterion to increase the automation ROI
The following category of test cases are not suitable for automation:
Following steps are followed in an Automation Process
Test Tool selection largely depends on the technology the Application Under Test is built on. For instance, QTP does not support Informatica. So QTP cannot be used for testing Informatica applications. It's a good idea to conduct a Proof of Concept of Tool on AUT.
The scope of automation is the area of your Application Under Test which will be automated. Following points help determine scope:
During this phase, you create an Automation strategy & plan, which contains the following details-
