The process is repeated until the component at the top of the hierarchy is tested. Breath testing is a test suite that exercises the full functionality of a product but does not test features in detail. Code Walk Through is the informal analysis of the program source code to find defects and verify coding techniques.
End-to-end testing is done after functional testing. The purpose behind doing end-to-end testing is that. A test harness is configuring a set of tools and test data to test an application in various conditions, and it involves monitoring the output with expected output for correctness.
Risk-based Testing is the term used for an approach to creating a Test Strategy that is based on prioritizing tests by risk. The basis of the approach is a detailed risk analysis and prioritizing of risks by risk level. Tests to address each risk are then specified, starting with the highest risk first. Preventative tests are designed early; reactive tests are designed after the software has been produced.
Decision table testing is used for testing systems for which the specification takes the form of rules or cause-effect combinations.
In a decision table, the inputs are listed in a column, with the outputs in the same column but below the inputs. The remainder of the table explores combinations of inputs to define the outputs produced.
The techniques of equivalence partitioning and boundary value analysis are often applied to specific situations or inputs. However, if different combinations of inputs result in different actions being taken, this can be more difficult to show using equivalence partitioning and boundary value analysis, which tend to be more focused on the user interface.
The other two specification-based techniques, decision tables, and state transition testing are more focused on business logic or business rules. A decision table is a good way to deal with combinations of things e. The difference between a pilot and beta testing is that pilot testing is actually done using the product by the group of users before the final deployment, and in beta testing, we do not input real data, but it is installed at the end customer to validate if the product can be used in production.
Testing technique: — Is a process for ensuring that some aspects of the application system or unit functions properly there may be few techniques but many tools. Testing Tools: — Is a vehicle for performing a test process. The tool is a resource to the tester, but itself is insufficient to conduct testing.

Component testing may be done in isolation from the rest of the system depending on the context of the development life cycle and the system. Most often stubs and drivers are used to replace the missing software and simulate the interface between the software components simply. A stub is called from the software component to be tested; a driver calls a component to be tested.
Here is an awesome video on Unit Testing. Testing the end to end functionality of the system as a whole is defined as a functional system testing. Random testing is often known as monkey testing.
In such type of testing data is generated randomly often using a tool or automated mechanism. With this randomly generated input, the system is tested, and results are analyzed accordingly. These testing are less reliable; hence it is normally used by the beginners and to see whether the system will hold up under adverse effects. In contrast to informal reviews, formal reviews follow a formal process.
A typical formal review process consists of six main steps:. The moderator or review leader leads the review process. He or she determines, in co-operation with the author, the type of review, approach and the composition of the review team. The moderator performs the entry check and the follow-up on the rework, in order to control the quality of the input and output of the review process.
The moderator also schedules the meeting, disseminates documents before the meeting, coaches other team members, paces the meeting, leads possible discussions and stores the data that is collected. Learn More about Review process in Video Tutorial here.
Structure-based testing techniques which are also dynamic rather than static use the internal structure of the software to derive test cases. For example, a structural technique may be concerned with exercising loops in the software. Different test cases may be derived to exercise the loop once, twice, and many times. This may be done regardless of the functionality of the software. After the software has changed or when the environment has changed Regression testing should be performed. A negative test is when you put in an invalid input and receives errors.
While positive testing is when you put in a valid input and expect some action to be completed in accordance with the specification. Re-testing ensures the original fault has been removed; regression testing looks for unexpected side effects. The experience of both technical and business people is important, as they bring different perspectives to the test analysis and design process.
Due to previous experience with similar systems, they may have insights into what could go wrong, which is very useful for testing. It depends on the risks for the system being tested. There are some criteria based on which you can stop testing. The primary purpose of the integration strategy is to specify which modules to combine when and how many at once.
