Part 2: Automated Testing Vs Manual Testing | 5 Most important Pros and Cons

Manual Testing

Manual testing is when a tester can test an application without having any prior programming expertise. Manual testing involves the test engineer testing the program as if he/she were a user to ensure it is bug-free and stable. On the other hand, automation testing is done by converting any manual test case into test scripts utilizing automation testing tools, and automation refers to the scripting or programming language used.

Software testing can be more efficient, effective, and comprehensive by using automation testing. Automation testing solutions are used by automation test engineers to automate manual design test cases without the need for human intervention. For more detailed information on the definitions, you can visit the first part of this blog. Here are the top 5 most important Pros and Cons of Manual Testing vs Automated Testing:

Pros of Manual Testing

  1. With manual testing, you can get fast and accurate feedback visually.
  2. Human resources investment is needed, however manual testing is less expensive since you don’t have to invest on automation technologies and processes.
  3. Manual testing enables for human observation, which can be more beneficial if the aim is enhanced user friendliness or improved customer satisfaction.
  4. To test a minor change, an automated test would require coding, which would be time-consuming. On the contrary, you can test manually very easily and conveniently.
  5. Manual testing is practical when test cases are executed only once or twice and there is no need for frequent repetition.

Cons of Manual Testing

  1. Since manual testing is executed by a human, it is a less reliable testing procedure.
  2. Manual testing method cannot be recorded, thefore it can not be reused.
  3. Manual testing requires much more time and significant human resources.
  4. Manual testing is prone to human errors and defects at all times.
  5. Certain procedures are difficult to accomplish in manual testing, which may demand more time throughout the software testing phase.

Automated Testing

Pros of Automated Testing

  1. When compared to a human tester, automated testing allows you to uncover more bugs while maintaining a high speed and efficiency.
  2. It is possible to record the automation process. This allows you to reuse and run the same testing tasks repeatedly.
  3. Automated testing can easily boost productivity by providing quick and accurate testing results.
  4. Since automated testing tools never fail to verify even the tiniest unit, testing coverage is expanded.
  5. When test cases are executed regularly over a lengthy period of time, automated testing is a viable alternative.

Cons of Automated Testing

  1. It’s impossible to gain insight into visual features of your UI such as colors, fonts, sizes, etc. without the human factor.
  2. Automation testing tools can be costly, thus raising the total budget of the testing project.
  3. Since automated testing does not include human observation, it cannot ensure user friendliness or a favorable consumer experience.
  4. Another big challenge in automated testing is debugging the test script. The expense of test maintenance is high.
  5. High levels of initial investment is required for automated testing tools.
