Exploratory testing is a hands-on approach in which testers are involved in minimum planning and maximum test execution. The planning involves the creation of a test charter, a short declaration of the scope of a short 1 to 2 hour time-boxed test effort, the objectives and possible approaches to be used. The test design and test execution activities are performed in parallel typically without formally documenting the test conditions, test cases or test scripts.
This does not mean that other, more formal testing techniques will not be used. For example, the tester may decide to use boundary value analysis but will think through and test the most important boundary values without necessarily writing them down. Some notes will be written during the exploratory-testing session so that a report can be produced afterward.
The relationship between test cases and requirements is shown with the help of a document. This document is known as a traceability matrix. Equivalence partitioning testing is a software testing technique which divides the application input test data into each partition at least once of equivalent data from which test cases can be derived.
By this testing method, it reduces the time required for software testing. White box testing technique involves selection of test cases based on an analysis of the internal structure Code coverage, branches coverage, paths coverage, condition coverage, etc. It is also known as Code-Based testing or Structural testing. Different types of white box testing are. Black box testing is the software testing method which is used to test the software without knowing the internal structure of code or program.
This testing is usually done to check the functionality of an application. The different black box testing techniques are. Static testing: During Static testing method, the code is not executed, and it is performed using the software documentation.
Dynamic testing: To perform this testing the code is required to be in an executable form. Verification is a process of evaluating software at the development phase. It helps you to decide whether the product of a given application satisfies the specified requirements. Validation is the process of evaluating software at the after the development process and to check whether it meets the customer requirements.
Integration testing is a level of software testing process, where individual units of an application are combined and tested. It is usually performed after unit and functional testing.
Test design, scope, test strategies, approach are various details that Test plan document consists of. System Testing: System testing is finding defects when the system undergoes testing as a whole; it is also known as end-to-end testing. In such type of testing, the application suffers from beginning till the end.
UAT: User Acceptance Testing UAT involves running a product through a series of specific tests which determines whether the product will meet the needs of its users. Retesting: It is a process of checking bugs that are actioned by the development team to verify that they are fixed.
The application is tested with a different set of values. Test Scenarios: A Test Scenario is any functionality that can be tested.
It is also called Test Condition or Test Possibility. Test Cases: It is a document that contains the steps that have to be executed; it has been planned earlier. In other words a written set of steps that should be performed manually. Latent defect: This defect is an existing defect in the system which does not cause any failure as the exact set of conditions has never been met.
Phantom is a freeware and is used for windows GUI automation scripting language. It allows us to take control of windows and functions automatically. It can simulate any combination of keystrokes and mouse clicks as well as menus, lists and more. Test Deliverables are a set of documents, tools and other components that have to be developed and maintained in support of testing. When the presence of one defect hides the presence of another defect in the system, it is known as fault masking.
This will resolve the issue and hide the defect of unhandled exception firing. A test plan can be defined as a document describing the scope, approach, resources, and schedule of testing activities and a test plan should cover the following details. It helps you to eliminate product risk in your project, and there is a simple yet crucial step that can reduce the product risk in your project. To get an expected test outcome, a standard procedure is followed which is referred to as Testing Type.
SQA focusses more on the software process rather than the software work products. It is a set of activities designed to make sure that the project manager follows the standard process. SQA helps test manager to benchmark the project against the set standards. RTM is prepared before test case designing. Requirements should be traceable from review activities.
Test Matrix : Test matrix is used to capture actual quality, effort, the plan, resources and time required to capture all phases of software testing.
Traceability Matrix : Mapping between test cases and customer requirements is known as Traceability Matrix. Both stubs and drivers are part of incremental testing.
In incremental testing, there are two approaches namely bottom-up and top-down approach. Drivers are used in bottom-up testing and stub is used for a top-down approach. In order to test the main module, the stub is used, which is a dummy code or program.
The key words control the processing. It is also used for the visualization of data processing. The cycle is repeated unless there are no errors found. Fuzz testing is used to detect security loopholes and coding errors in software.
In this technique, random data is added to the system in an attempt to crash the system. If vulnerability persists, a tool called fuzz tester is used to determine potential causes. This technique is more useful for bigger projects but only detects a major fault. None of the characters should get truncated. Junk characters should not be added. The code coverage testing tool runs parallel while performing testing on the actual product. The code coverage tool monitors the executed statements of the source code.
When the final testing is done, we get a complete report of the pending statements and also get the coverage percentage. In simple terms when a defect reaches the end customer, it is called a failure while the defect is identified internally and resolved; then it is referred to as a defect. Black box test cases are written first as to write black box test cases; it requires project plan and requirement document all these documents are easily available at the beginning of the project.
While writing white box test cases requires more architectural understanding and is not available at the start of the project. Bottom-up testing is an approach to integration testing, where the lowest level components are tested first, then used to facilitate the testing of higher level components.
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. Learn More About Testing Tools here.
Component testing, also known as unit, module, and program testing, searches for defects in and verifies the functioning of software e. 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.
