What You Need to Know About Software Testing

Definition :

Software testing is the process of identifying and fixing defects in a software application to ensure it meets the specified requirements and customer expectations.

All the software applications are developed to support the customer business, If there is any defect found in the software it will leads to failure of software and eventually it will affects the customer’s business. In order to deliver a defect free software application to customer we have to go for Software Testing.

Types Of Software Testing :

1. White Box Testing

2. Black Box Testing

3. Grey Box Testing

White Box Testing :

It is software testing process in which internal structure, design & code of application is tested. The tester should have knowledge of all logic written in the application.

This testing is done by the Developers, hence it is also called as Open Box Testing.

Black Box Testing :

It is one of Software testing process in which the tester’s will tests the Functionality Of An Application against the Customer requirement. It is done by Test Engineers, also called as Behavioral testing or Functional testing.

Grey Box Testing :

Grey Box Testing is testing where tester has limited knowledge of the internal code or design and uses that partial knowledge to test the application.

It is combination of both White Box Testing & Black Box Testing. This testing is done by DevOps engineers.

It is very rare in actual scenario of testing, say doing this is less because software application is already fully tested in Black Box Testing phase only.

Advantages Of Software Testing :

1. Software testing makes sure the software works well and is reliable.

2. It finds problems early, which saves time and money.

3. It keeps the software safe from security issues.

4. It makes the software easy and smooth to use.

5. It helps people trust and feel confident in the software.

Limitations Of Software Testing :

1. 100% testing of all scenarios is not possible.

2. Some defects may remain hidden even after testing.

3. Testing tools and resources can be expensive.

4. Tight deadlines may reduce testing quality.

5. Real world usage may differ from the test environment.

When we need to go for Software Testing :

1. When developing new software before releasing it to users.

2. After adding new features or updates to existing software.

3. After fixing the bugs to make sure the fix works and doesn’t break other parts.

4. Before delivering software to customers.

5. When moving software to a new platform or environment.

6. After major changes in requirements or design.

Summary Point :

Software testing checks if the software works properly and meets what the customer needs. It helps find and fix problems so the customer gets good quality software.
