Software testing

Software testing:
Checking the performance and quality of the software, Aim of software testing was providing error free software to the customer and fulfill all the requirements given by the customer. Software testing is not only finding the mistakes in the software at the same time improving the efficiency of the software.
Software testing is the process of evaluating and verifying that a software product or application does what it’s supposed to do. The benefits of good testing include preventing bugs and improving performance.
Software errors can make time loss, financial loss and human loss too so testing the software was very important. When we think about quality, Organizations have to focus on testing applications and fix the bugs that testing reveals before releasing the product. When the team resolves issues before the product reaches the customer, the quality of the deliverable increases.
Software testers use a combination of manual testing with automated tools. After conducting tests, the testers report the results to the development team. The end goal is to deliver a quality product to the customer, which is why software testing is so important.

Types of Software Testing:
Two different approaches for software testing: manual testing & automation testing. Each approach carries its own set of advantages and disadvantages
**Manual Testing: **Testing software manually by humans without any automation tool or script.They play the end-user role and try to find as many bugs in the application as quickly as possible.

Automation Testing: Testing software using tools or scripts that automatically interact with the software. The human tester only needs to execute the script and let it do the rest of the testing.

Automated testing Vs Manual testing

Speed and efficiency:
Automated testing is typically faster than manual testing.
Increases productivity and reduces testing time for most apps/websites.
Cost considerations:
Higher initial setup costs due to purchasing automation tools, training, and preparing tutorials.
Offers long-term cost savings despite the initial investment.
Regular script maintenance can be costly, especially for frequently changing apps/websites.
Suitability for different tasks:
Ideal for repetitive tasks, reducing manual inefficiency and human error.
Not suitable for all testing types - user interface, documentation, installation, compatibility, and recovery tests may be better conducted manually.
Even with automation, some manual testing is usually necessary.
Testing approaches
White Box testing
Focuses on the internal structure and logic of the code
Black Box testing
Evaluates the software's functionality without looking at the internal code structure
Grey Box testing
Combines white and black box testing elements, offering a more comprehensive approach
Software Testing Process:
