Software Testing: The Significance



What is Software Testing?

Software Testing is defined as an activity of testing a software to check whether the actual end results match the expected ideal results and to make sure that the software is bug free. Software testing can also help to find out defects, gaps or missing requirements. It can be done either manually or using automated tools.

Why is Software Testing Important?



It is very much important because software bugs or errors could be dangerous or cause huge loss. There occurred many incidents which caused monetary or human loss due to software bugs:
  • In the year 2015, the fighter plane F-35 fell down.
  • Due to software error in the airbag sensory detectors, Nissan car companyhas to recall over 1 million cars from the market.
  • Some of the Amazon’s third party retailers found their product price has been reduced to 1p due to a software defect. They had met with big losses.
  • In 1994, China Airlines Airbus A300 crashed due to a software fault, killing 264.
  • A software bug caused the bank accounts of several customers of a popular U.S. bank to be credited with huge amounts, in 1996.



There are two types of Software Testing:

Manual Testing

Manual testing is the testing of a software manually, that means without using any automated tool or script. In manual testing, the tester tests the entire software application like an end user. The different types of manual testing are:
  • Unit testing
  • Integration testing
  • System testing
  • User acceptance testing.

To ensure the perfection of the software, testers use test plans, test cases, or test scenarios.

Automation Testing

In Automation testing, the testers use another software or scripts in order to find the bugs.

Automation Benefits:


  • To reduce repetitive works:

Repetitive work can be tedious and boring when it is done manually. There may be chances to make mistakes when doing the same task over and over. Some examples of repetitive works are: running regression tests, and entering the same test data again and again.

  • High consistency and repeatability: 

When people do same tasks repeatedly, they tend to do it in a slightly different way each time, but when a tool is used, it can exactly reproduce what it did earlier, so the result and output will be consistent.

  • Objective assessment:

 When a person calculates a value from the software or reports, they may omit something by mistake, but by a testing tool, the assessment is more repeatable and hence, consistently calculated.

  • Easy access to information:

 Testing tools can present the information about testing visually like charts or graphs in spreadsheets. So it’s much easier to understand about the testing progress and details through visual reports while using testing tools.

Disadvantages:

  • Unrealistic Results:

There may be chances for unexpected outcome while using software testing tools. Hence, it is highly important to have a realistic aims and objectives for what the testing tool can perform.

  • People can make mistakes at the beginning:

While introducing some new tool into an organization, a number of staff have to use it and to be familiar with it. After that only, the tool may turn to be beneficial and effective. Some people can raise objections when using a new tool. All these issues should be handled in a tactic way to make the tools useful for a firm.

  • People may depend a lot on the testing tool:

Even though a testing tool can simplify the testing tasks, and offer much help, it can’t be depended much as it’s simply a software and it has its own limitations. It can never replace the human intelligence.
