TESTING
Testing plays a vital role in software development and also necessary and important stage in software development life cycle. Testing the software product can be improved the software quality, reliable, capacity and performance in efficient.
What is Software Testing?
Software Testing is the process of verifying and validating whether a software application or product meets the business and technical requirements that guide its design and development.
It is the process of executing a program or application with the intent of finding defects or bugs in it.
It can be carried out Manually or by using Automation tools. It is a method to check whether the actual software products matches expected requirements and to ensure that software defect free and is to identify the errors or bugs or any missing requirements.
Benefits of Software Testing
- Cost-effective
- Security
- Product Quality
- Customer Satisfaction
Quality
The quality of your product is high,it is important for the customer.
Customer satisfaction
When you realize that it would be best that quality was
controlled from the start,then It pays off to produce a higher quality product from the starting of the software testing right you can guarantee that your product is valuable and reliable.
Methods of Testing
- Manual Testing
- Automation Testing
Manual Testing:
It is the process of Testing the software manually to find the defects.In this process, testers execute the test cases and generate the reports manually without using any automation tools.
Automation Testing:
It is the process of testing the software using an automation tools to find the defects, to control the execution of tests and then compares actual test results with predicted or expected results.
Types of Testing:
- Functional Testing
- Non-Functional Testing
Functional Testing:
It is a type of testing which verifies that each function of the software application operation in conformance with the requirement specification.
Non-Functional Testing
It is a type of testing to check Non-Functional aspects(performance, usability, reliability,etc) of a software application, the verifies the attributes of the system such as memory leaks, performance or robustness of system.
LEVELS OF TESTING:
- Unit Testing
- Integration Testing
- System Testing
- Validation Testing
Software Testing Tools:
The following tools can be used for automation Testing:-
- HP Quick Test Professional
- Selenium
- IBM Rational Functional Tester
- Silk test
- Test Complete
- Testing Anywhere
- VS Test Professional
Etc.
Why Manual Testing is Important?
- To compensate, software testing plans generally employ a range of test methods that involve both manual and automated testing, which enables all requirements to be addressed.
- Automation testing best for routine and iterative testing, which can be extremely time consuming and tedious if performed manually.
- Manual testing, however, works better in areas where automation cannot replicate the intuitiveness, overall comprehension, and iterative assessments that a person can bring to the process.
- In addition to this, some forms of testing can only be performed manually, and both the setup of automation testing and assessing the results also needs human intervention.
When we prefer Manual Testing over Automation Testing?
The following scenarios are manual testing over automation testing:
- If the project is in initial development stage.
- The testing user interface especially their visual aspects.
- It exploratory or Adhoc testing needs to be performed.
- If the test case is not automation.
- Example captcha.
When we prefer Automation Testing over Manual Testing?
The following scenarios are automation testing over manual testing:
- To handle repetitive and time consuming tasks
- To do parallel testing
- To do non-functional testing like load, performance, stress testing
- To avoid human errors
