3. Types of Testing

3.1. Unit Testing
3.1.1. Definition
Unit testing (microsoft) is a first level of software testing where a unit/component of software was tested to match requirements. Generally Unit testing is performed by developers or its peers. Sometimes independent software testers are used to do Unit testing. Unit testing is also referred as component testing.
Before integrating the modules, the unit or piece of code is identified as a component and complete testing was carried out to ensure expected output. I.e., for any function or procedure a proper output is expected when an input was given. Also it should handle negative scenarios or failures during execution of unit testing.
3.1.2. Benefits

• Good unit test plan contains all scenarios/path covered and catches error/defect when a code was modified.
• Impact analysis is not required at this level of testing, as only a piece of code was modified.
• If an error was found at this level of testing, the latest changes needs to be verified. It simplifies testing efforts at later stage. 3.1.3. Tools used
Various tools and frameworks are used based on programming language.
3.1.4. Test Case
Identifying test case for unit testing includes the set of inputs, preconditions to execute the unit/module, and expected output. The test procedure should clearly explain the flow of the test condition and expectations with input conditions.
In general, two types of test case are derived for Unit testing,
1. Positive Test case
2. Negative Test Case
3.1.5. Logical Coverage methods
To identify test case, logical coverage has to be covered. It can be achieved by using the following methods,
3.1.5.1. Boundary Value Analysis
• A boundary value is one which indicates the border (or the limit) of a value
• Test cases that explore boundary values have the highest payoff in terms of detecting bugs, as the most common errors occur at the boundary

• Business acceptance testing – External/ Customer identified potential users test the product.
• Alpha testing – Similar to Internal user acceptance testing, group of development team test.
• Beta testing – In client environment testing takes place by group of customers/end users.
• Operational acceptance / Production acceptance testing – final test to release product for production.
• Contract acceptance testing – Customer agreed requirements verified.
• Compliance acceptance testing – Legal / Regulations are verified.
From all types of testing, feedback is received and the software is updated. The output of this testing is either acceptance of the product or rejection of the product. In live environment, the changes are marked and are migrated to production in iterative process.
System component testing are using tools in this phase of testing and end-user requirements are verified manually similar to end-user actions.
4. Tools list
Below are few tools used for testing at various levels of software testing. But these tools are not limited to and many other tools are available for testing. 5.

    TEST SPECIFICATION Testing is an important part of software development life cycle. It is performed to ensure quality of the developed system. Testing includes a set of investigative activities that can be planned in advance and conducted systematically, to assure the stakeholder that system ful lls all the requirements gathered during requirement gathering phase. Software testing is one of the key elements in software projects that is often referred to as veri cation and validation. Veri cation refers to the set of activities that ensure that software correctly implements speci ed functionality.…

    After the acceptance of the users the inputs of the system are validated. Software units in of an application are those modules and routines that are developed and then integrated to form a specific functionality. Unit testing is done on single modules, independent of one another to find or detect errors. This enables the tester to find errors or bugs in the program and through these bugs or errors resulting errors in integration between different modules initially…

    The design process activities include architectural design, abstract specification, interface design, component design, data structure design and algorithm design. Software validation is a process that assures that a certain system conforms to the specifications and customer/user requirements. It involves review processes and system testing. The system testing involves executing the system using test cases extracted from the specification of the real data to be processed by the system. The testing stages include unit testing, system testing and acceptance…

    There are three core principles in developing PICT which are speed in generating test, ease of use and extensibility of core engine. PICT take input of plain-text file that specified by tester as test factor (parameters) and test factor values (values of parameter) (Czerwonka, 2006). Two phases need to be passed through in order to generate test cases in PICT, preparation and generation. Firstly, all information needed in generation phase need to be computed in preparation phase. This information includes parameter-interaction structure that defined interaction of values to be covered.…
