What is Software Testing?

Software testing is a process of executing a program or application with the intent of finding the software bugs. It can also be stated as the process of validating and verifying that a software program or application or product: Meets the business and technical requirements that guided it's design and development.

Verification :-

Verification is the process to make sure the product satisfies the conditions imposed at the start of the development phase. In other words, to make sure the product behaves the way we want it to.

Validation :-

Validation is the process to make sure the product satisfies the specified requirements at the end of the development phase. In other words, to make sure the product is built as per customer requirements.

Manual Testing

Acceptance Testing :-

Acceptance Testing is a level of the software testing where a system is tested for acceptability.The purpose of this test is to evaluate the system’s compliance with the business requirements and assess whether it is acceptable for delivery.

White Box Testing :-

White Box Testing (also known as Clear Box Testing, Open Box Testing, Glass Box Testing, Transparent Box Testing, Code-Based Testing or Structural Testing) is a software testing method in which the internal structure/ design/ implementation of the item being tested is known to the tester. The tester chooses inputs to exercise paths through the code and determines the appropriate outputs. Programming know-how and the implementation knowledge is essential. White box testing is testing beyond the user interface and into the nitty-gritty of a system.

Black Box Testing :-

Black Box Testing, also known as Behavioral Testing, is a software testing method in which the internal structure/ design/ implementation of the item being tested is not known to the tester. These tests can be functional or non-functional, though usually functional.

Unit Testing :-

Integration Testing is a level of software testing where individual units are combined and tested as a group.

System Testing :-

System Testing is a level of the software testing where a complete and integrated software is tested.The purpose of this test is to evaluate the system’s compliance with the specified requirements.

Integration Testing :-

Automation Testing

In software testing, test automation is the use of special software (separate from the software being tested) to control the execution of tests and the comparison of actual outcomes with predicted outcomes.

Manual testing is performed by a human sitting in front of a computer carefully executing the test steps. Automation Testing means using an automation tool to execute your test case suite. The automation software can also enter test data into the System Under Test , compare expected and actual results and generate detailed test reports.

Test Automation demands considerable investments of money and resources. Successive development cycles will require execution of same test suite repeatedly. Using a test automation tool it's possible to record this test suite and re-play it as required. Once the test suite is automated, no human intervention is required . This improved ROI of Test Automation.

Goal of Automation is to reduce number of test cases to be run manually and not eliminate manual testing all together.

Selenium Testing :-

Selenium is one of the function testing tool & It is an open source project that allows testers alike to develop functional tests to drive the browser. Selenium can work on any browser that supports JavaScript since Selenium has been built using JavaScript. One can develop script in selenium and reduce the manual testing efforts.

Non Functional Testing

In non-functional testing the quality characteristics of the component or system is tested. Non-functional refers to aspects of the software that may not be related to a specific function or user action such as scalability or security. Eg. How many people can log in at once? Non-functional testing is also performed at all levels like functional testing.

To address this issue, performance testing is carried out to check & fine tune system response times. The goal of performance testing is to reduce response time to an acceptable level. Likewise, you might have seen the message like "Server Busy". Hence, load testing is carried out to check systems performance at different loads i.e. number of users accessing the system.
