Automation Software Testing; the Alternate Solution to Tedious Testing!
This is the era of highly interactive and responsive software processes. And that is why Automation Testing is currently the key player in the industry. The term refers to the practice of using a software tool to run repeatable tests against the application to be tested. In software testing, test automation is the use of special software to control the execution of tests and the comparison of actual outcomes with the predicted outcomes.
As opposed to the more traditional manual testing, where a human is required to sit before a computer and carefully execute the test steps, Automation Testing allows the use of an automation tool to execute the test case suite.
Automated testing tools are capable of the following: they execute tests, report outcomes and compare results with the earlier test runs. Perhaps the biggest edge offered is that these tools can run repeatedly, at any time of the day, carrying out tests that are simply tedious and impractical to be performed manually. Meanwhile, the method or process being used to implement automation is called a test automation framework.
Automated software testing is vital to the industry for many reasons. To run Manual Tests on the entire workflows, fields and negative scenarios is much time and cost consuming. It is also difficult to test for multilingual sites manually. Manual Testing carries the risks of becoming tedious due to its repetitive nature and hence is error prone. With regards to improving the long-term efficiency of a software team’s testing processes, Automation Testing has more advantages.
Here is a list of the advantages of Automation Testing over Manual Testing:
Automation increases the speed as it is 70% faster than the manual testing
Automation helps increase the Test Coverage
Frequent regression testing is possible
Facilitates rapid feedback to developers
Virtually unlimited iterations of test case execution
Support for Agile and extreme development methodologies
Disciplined documentation of test cases
Customized defect reporting
Find defects missed in manual testing
Reliable in results and ensures Consistency
Saves Time and Cost
Human Intervention is not required while execution
Reusable test scripts
Test frequently and thoroughly
More cycle of execution can be achieved through automation
Enables early time to market
However, even as Automation Testing can reduce the number of test cases to be run manually, it can never totally replace manual testing. Despite the many advantages of Automation Testing, they cannot be utilized in all scenarios. High Risk – Business Critical test cases, repeatedly executed test cases, time-consuming test cases and those that are very tedious or difficult to perform manually are the appropriate cases to undergo automation testing.
There are times when Manual Testing is more appropriate for the case. Test Cases that are newly designed and not executed manually at least once before, those with frequently changing requirements and the cases which are executed on an ad-hoc basis are best handled manually. For instance, if the application’s user interface is expected to change considerably in the near future, then any automation might need to be rewritten anyway. Also, sometimes there simply is not enough time to build test automation. For the short term, manual testing could be more effective. Similarly, if an application has a very tight deadline, or there is currently no test automation available, and it’s imperative that the testing gets done within the given time frame, then manual testing is the best solution.
There are a number of commercial and open source tools available for assisting with the development of test automation. Selenium is possibly the most widely-used open source solution. UFT (earlier known as QTP) is the commercial counterpart of Selenium and is a licensed HP tool that is mostly preferred by the Tier-1 companies worldwide. Knowledge and skills in these popular Automation Testing Tools help the candidates gain an edge in their own respective areas. Moreover, industry experts recommend aspiring Software Testers to grab the necessary qualification for bagging the dream job!
