Why Automation Testing is preferred in IT Companies?

Automation Testing

Traditionally, once software engineers develop a software application it is sent to the tester. Then the tester tests it, this can also be done by an end-user of the application. But a software tester will consider a lot of technical parameters while testing an application, anyhow the process is slow and recursive that is the process needs to be done multiple times, which again takes a lot of time. This was accepted by the software companies when they were working in a waterfall model of software development life cycle. But today, almost all of the companies are working in agile methodology. To understand the significance of Automation Testing, let’s just take a look at agile and how it works.

What is Agile and how it works?

Well, Agile is a methodology where everything works fast and simultaneously, which makes automation a perfect pick for it. When a project has got approved by the manager then the business analyst gathers all the details of the application, but if it is expected to get all the information of the application then it might take a lot of time where the technical team would sit idle till, along with that, the waterfall model requires a huge documentation. Agile doesn’t work this way, all the technical employees are expected to work or to start the work with the limited information that they have received from the BA and all the tasks are done in a cyclic approach. This cycle is called the Sprint cycle, where the entire team builds a part of an application within a limited period and that small portion will be shown to the client.

The Significance of Automation Testing in Agile

Here comes the automation testing to save time, because in agile everything is developed in a sprint cycle that has a cyclic time of 2 – 3 weeks. When the time is over then the developed part of the application is demonstrated to the client and requires the client’s approval. When the client approves or demands a change in the application then the developer does the job, but here comes the problem when the tester attempts to test the application. The tester needs to repeat all the steps/processes that have been done in the previous cycle, to overcome this automation testing software tools have been developed. Selenium is one such tool that has an upper hand over all the other web automation testing tools in the market. Due to which Selenium training in Chennai and other Indian cities has popularized and also sought by many college grads and working professionals. Computerization is the need for each business now. It helps in expanding efficiency and furthermore helps in giving consumer loyalty. Computerization included a bit of leeway is limited the opportunity of human mistakes and gives the most extreme precision as a result. Computerizing business exercises requiring little to no effort makes the establishment of an association more grounded. With computerization having a major effect lately, an inquiry that emerges is – what befalls the HR if each work gets robotized. With the development of clothes washers, vacuum cleaners and so forth interest for cleaners still exists. Robotization supplants numerous undertakings yet additionally makes space for a lot of openings for work and administrations.

Advantages of Selenium Automation Testing

Selenium is much faster than the work done manually, the code written once can be reused for multiple times. Having this as an advantage, automation testers write the automation testing script and reuse it when required, it is also easy to test it even after once the Sprint cycle has been over. Due to this reason automation testing is preferred for the agile environment. Apart from these, it is much easier to pass the test data, especially from the excel sheet where Selenium does the job at no time. Even to test an application form at least one time, Selenium is preferred as it is much faster. Then comes the cross-platform testing and CI/CD tools, Selenium has become the perfect blend for automation testing as it can be run through Continuous Integration and Continuous Deployment (CI/CD) tools like Jenkins along with all the code can be pushed to the version controlling software applications where it can be stored in the remote repositories. 

Till now, agile has been proved to be one of the effective approaches for SDLC and automation acts as a perfect companion for this. So this the best time to bet on automation testing as it has a lot of got potential opportunities for the manual testers and also for developers.
