What Is Software Testing?

Software Testing is the activity that is aimed at evaluating the capability of a program or system and determining that it meets its expected results. Simply put, it is the process of executing a program or system  to find errors or mistakes. 

The problem in software testing stems from the complexity of the software; we cannot wholly test a program with mild complexity. Software Testing is something more than just debugging. The purpose of software testing can be quality assurance, reliability estimation or verification and validation.

Unlike physical systems, most software defects are design errors and not manufacturing defects. Once the software is ready, the design defects remain concealed until activation. Therefore, software testing becomes an integral part of removing any of the bugs that may have appeared. You first have to become a software tester to learn about the detailed concept. 

Why Do We Need Software Testing?

Software testing is broadly dispersed in every phase of the software development cycle. More than 50% of the development time is spent in its testing.

Software testing is needed in software development for the following purposes:

1. For Reliability Estimation—Software reliability is related to many aspects of the software, including its structure and the amount of testing it has been subjected to. Testing can serve as a statistical sampling method to gain failure data for reliability estimation based on an operational profile.

2. To Improve Quality - As computers and software are used in critical applications, the outcome of a bug can be severe. Bugs in critical systems have caused airplane crashes, halted trading on the stock market, and even worse. Bugs can cause massive disasters. 

Quality means conformance to the specified design requirement. To be correct, the minimum requirement of quality means performing as required under specified circumstances. Debugging is a narrow view of software testing, and the programmer performs it heavily to find design defects.

3. For Verification and Validation - Verification and validation are other vital purposes of software testing. Testers make claims based on interpretations of the testing results. We can also compare the quality of different products under the same specification based on results from the same test. Good software testing provides measures for all relevant factors.

What Is Manual Testing?

Manual Testing is a procedure done to determine the defects in software that have been developed. In this type of testing, the tester manually checks the features of the given application, program, and software to ensure the proper functioning of that application, program, or software. 

In Manual Testing, a tester executes the test cases and generates test reports without using automation testing tools. It is performed by an experienced testing professional as a preparatory method that must be completed before the various experiments are automated. This method additionally checks the need for mechanized testing. 

What Are the Advantages of Manual Testing?

Here are a few advantages and disadvantages that you have when you opt for manual testing-

1. Cost-Effective in Short-Term Scenarios: Buying software automation tools can turn out to be very expensive. With the help of manual testing, you won’t have to invest an insanely huge amount of money in testing
2. Bugs Related to User-Handling are Caught More Easily: Automated tests are literally robotic. They fail to act as an actual end-user would. On the other hand, manual testing permits the developing program to be tested and used as it would be used on its launch or final delivery. Any bugs and defects that may pop up as soon as a user handles the given software in a certain way are more likely to be wedged with the help of manual testing.
3. Manual Testing is Adaptable: In manual testing, you can swiftly test and see the outcomes. Automatic tests take more time to set up and adjust to the change, which prevents you from testing ideas swiftly and conveniently.

4. Effortless recruitment: In manual testing, the skills required are more generalized, allowing a wider pool of candidates to perform the tests, thereby simplifying the hiring process and making it more efficient.

Manual Testing Cons

• Incomplete defect detection: In manual testing, there is no guarantee of achieving 100% test coverage, which means some defects may go undetected.
• Non-recordable process: You will not be able to record the manual testing process. Hence, you can’t use this process again.
• Time-consuming: Manual testing is an extensive activity that requires a significant amount of time to develop test cases manually, ensuring all functionalities are covered and tested.
• High expertise needed: While manual testing can be performed by anyone, certain complex cases demand a higher level of expertise.

What Is Automation Testing?

Before we discuss manual testing vs. automation testing, let’s first understand Automation Testing. It is a type of testing performed with the help of an automation tool to write and then execute a tester's test scripts and test cases. The critical purpose of Automation Testing is to lessen the number of test cases run by manual testers but not discard Manual Testing altogether.

If the software's intended expectations and outcomes align, then it is understood that your project is behaving as it should and that your program is most likely bug-free. If the two are not in accordance, that indicates an issue that needs to be addressed. 

You'll have to examine your code carefully, change it, and continue to run the necessary tests until the actual results align with the expected results.
