What is Manual Testing?
Manual testing:- is the oldest and most rigorous type of software testing. Manual testing requires a tester to perform manual test operations on the test software without the help of Test automation. Manual testing is a laborious activity that requires the tester to possess a certain set of qualities; to be patient, observant, speculative, creative, innovative, open-minded, resourceful, un-opinionated, and skillful.
and more about manual testing:- Manual Testing is a type of software testing where Testers manually execute test cases without using any automation tools. Manual testing is the most of primitive of all testing types. Manual Testing helps find bugs in the software system.
Goal of Manual Testing:-
The goal of Manual Testing is to ensure that the application is error free and it is working in conformance to the specified functional requirements. Test Suites or cases are designed during testing phase and should have 100% test coverage.
Manual Testing types:
there are many types of manual testing but mostly using the manually testing are:-
1. Black Box Testing.
2. White Box Testing.
3. Unit Testing.
4. System Testing.
5. Integration Testing.
6. Acceptance Testing.
- Black box testing:- Black box testing takes an external perspective of the test object to derive test cases. These tests can be functional or non-functional, though usually functional. The test designer selects valid and invalid input and determines the correct output. There is no knowledge of the test object’s internal structure.
- White Box Testing:- White box testing is a security testing method that can be used to validate whether code implementation follows intended design, to validate implemented security functionality, and to uncover exploitable vulnerabilities.
- Unit Testing:- The primary goal of unit testing is to take the smallest piece of testable software in the application, isolate it from the remainder of the code, and determine whether it behaves exactly as you expect. Each unit is tested separately before integrating them into modules to test the interfaces between modules. Unit testing has proven its value in that a large percentage of defects are identified during its use.
- System Testing:- Usually software is only one element of a larger computer based system. Ultimately, software is interfaced with other software/hardware systems. System testing is actually a series of different tests whose sole purpose is to exercise the full computer based system.
What do you verify in System Testing ?
System testing involves testing the software code for following:-
- Testing on fully integrated applications in order to test how components interact with one another and with the system as a whole. This is also called End to End scenario testing.
- Very thorough testing of every input in the application to check for required outputs.
- Testing of the user’s experience with the application from start to finish.
Comparison of Manual and Automated Testing
Automation Testing is use of tools to execute test cases whereas manual testing requires human intervention for test execution.
Automation Testing saves time, cost and manpower. Once recorded, it’s easier to run an automated test suite when compared to manual testing which will require skilled labor.
Any type of application can be tested manually but automated testing is recommended only for stable systems and is mostly used for regression testing. Also, certain testing types like ad-hoc and monkey testing are most suited for manual execution.
Manual testing can be become repetitive and boring. On the contrary, the boring part of executing same test cases time and again is handling by automation software in automation testing.
Manual testing is an activity where the tester needs to be very patient, creative & open minded.They need to think and act with an End User perspective.
