Introduction to Selenium Testing

What is Selenium Testing?

• Software testing is a very important part of
  software development life cycle. It is a phase
  where the bugs from the software are found. Then
  these bugs are fixed and this process enhances
  the quality of the software. A decade ago, the
  manual testing process was dominant and was used
  primarily for finding defects. However, the
  manual process is error-prone and time consuming.
  Hence, the testing process was automated and
  automation testing discipline was born. Selenium
  Testing is a very popular tool which every
  software tester needs to know.

• Automation in Testing
• When a defect is found in a software, the
  developer makes changes in the source code to fix
  it. Sometimes this can result in creeping defects
  in other parts of the software which were working
  perfectly before the bug was fixed. To make sure
  that this doesnt happen, other related
  parts/modules must be tested again after fixing
  bugs. In this fashion, parts of software get
  tested over and over again. This is called
  regression testing. This is a time-consuming,
  error-prone and boring process when done
  manually. Hence, regression test cases are always
  automated so that they can be run any number of
  times based on the requirements. This improves
  productivity too.

• There were many test automation platforms. Quick
  Test Professional(QTP), Selenium Web Driver are
  some of the names. These softwares allow the
  software tester to run the application and record
  the test cases. Because the test cases are
  recorded as a script they can be modified easily
  later on. One can perform data-driven testing
  with a lot many input records/data.

• Popularity of Selenium Testing
• Selenium is a popular software testing tool in
  the automation space. Since the beginning,
  Selenium has attracted a lot of fans due to its
  open source nature. Being open source, Selenium
  does not have any license cost per say. If any
  software testing team wants to try their hand at
  it, it is easily possible. First the team can use
  the open source software and build their own
  custom automation test framework. If this works
  well they can continue or shift to more costly
  commercial tools available.

• Selenium web driver is a more focused tool for
  web application testing. The scripts generated
  are in Java language. Java being a popular
  application development language, the adoption of
  selenium testing tools was easy. Though started
  with Java, Selenium 4 supports many other
  languages like Java Script, Python, Ruby, Kotlin,
  C etc.

• What does one need to learn before Selenium
  Testing?
• One cannot just start learning Selenium because
  there are a lot of job opportunities in the
  market. You must have knowledge of a couple of
  things before you can start with it. As Selenium
  testing is used in the domain of software testing
  and quality assurance, one must be aware of the
  software testing discipline itself.

• Software Testing as a discipline consists of
  various testing techniques like black box
  testing, white box testing, integration testing,
  system testing. The process involves various
  aspects like test planning, test cases design,
  test execution, defect management and so on. One
  needs to master these concepts first. Along with
  them, knowledge of a programming language like
  Java, SQL to handle databases, knowledge of
  HTML/web apps is essential. On this foundation,
  learning selenium testing is easy.

• Texceed offers the best course in software
  testing which is very comprehensive. It covers
  all these aspects starting from Java programming,
  SQL, and software testing techniques(also called
  manual testing) before covering selenium testing
  in depth. Here is the link to see more details.

• Conclusion
• As Selenium Testing is used in the domain of
  software testing and quality assurance, one must
  be aware of software testing discipline itself.
