Today we will try to discuss why Software testing is necessary, how these software tests are being performed, how software testing methodologies work and why is software testing important.
Software testing is an investigation conducted in order to provide stakeholders with information about the quality of the software product or service under test. Software testing can also provide an objective, independent view of the software solution to allow the business to appreciate and comprehend the risks of software implementation. Test techniques include the process of executing a program or application with the intent of finding software bugs, and verifying that the software product is fit for use.
Why Software Testing is Important in SDLC?
The software is an inseparable part of our daily life. We also encounter problems when using them. There is much software that contains errors and does not meet our expectations. Even these errors sometimes reach such a dimension. Therefore, the correct and effective implementation of the software testing process as what we do at Terkwaz Business Solutions is very important.
The person makes a mistake in the software development life cycle and this causes a defect in the software program. The flaw also causes the software not to do what it needs to do or to do something different. This causes a malfunction in the software system. If the software test is carried out carefully, it prevents errors from turning into faults. In addition, the software test determines the quality of the software in terms of functional and non-functional requirements. The number and significance of errors found through software testing are also used to determine trust in the software. A well-designed and successful software test can reduce the perception of inaccurate risky software.
When the errors found in the software tests are corrected, there is a feeling that it is even better quality software. However, the software process can be improved with lessons learned during the test process and the software development process can be handled by considering the errors. Software testing for such reasons; software development process as part of quality assurance activities.
The common idea is that the software test is merely the provision of tests. The software test run is an important part of the test, but not all software test work is run. There are also works related to the test performed before and after the software tests are run.
Different Test approaches
Software testing is a pool of knowledge and endorsement and it is a widely used process all around the world. Terkwaz Buiness Solutions offers a number of software testing services. You might wonder what are the different types that exist.
This is a type of black-box software testing that is based on the specifications of the software that is to be tested.
Let’s learn about each one of them in detail:
Unit testing service: A unit is the smallest testable part of any software product. It usually has one or a few inputs and a single output. It is a level of software testing where individual units/components of the software are tested. The main purpose is to validate each unit of the software product, performs as designed.
Integration testing service: It is a level of software testing where individual units are combined and tested as a group. The main purpose of this type of software testing service is to expose faults in the interaction between integrated units.
System testing service: It is a level of software testing where the complete and integrated software is tested. The purpose of this software test is to evaluate the system’s compliance with the specified requirements. It is a series of different tests whose sole purpose is to exercise the system.
Interface testing service: It is a level of software testing services which verifies whether the communication between two different software is done correctly.
Regression testing service: Regression testing verifies that a code change in the software does not have an impact on the existing functionality of the product.
User-acceptance testing service: It is a level of software testing where a system is tested for acceptability. The sole purpose of this test is to evaluate the system’s compliance with its business requirements and assess whether it is acceptable for delivery. It checks whether the software can handle the required tasks in real-world scenarios.
Non-Functional Testing involves testing software products from the requirements which are nonfunctional in nature but important such as performance, security, user interface, etc.
Let’s learn about each one of them in detail:
Documentation testing service: It helps to estimate the required testing efforts and track the requirements. Software documentation includes a test plan, test cases, and requirements section. It tests the documented artifacts.
Installation testing service: It is a type of software testing and quality assurance work in the software industry that converges on what customers will need to do to install and set up the new software successfully. It checks if the software application is successfully installed and is working as expected. The software testing process may involve full, partial or upgrades install/uninstall processes.
Performance testing service: It is defined as a type of software testing service that is used to ensure that the software applications will perform well under their expected workload. Performance testing is considered as a heart of Non-functional software testing.
Reliability testing service: It assures that the software product is fault free and is reliable for its intended purpose. It is about exercising an application so that the failures are discovered before the system is deployed.
Security testing service: It is a variant of software testing which ensures that the system and applications of the organization are free from loopholes. Security testing is about finding all possible weaknesses of the system which might result in a loss of information.
What is manual testing?
Software Manual Testing means testing of an application manually by a human. A Quality Assurance Specialist performing manual testing ensures that an application is working properly by following conditions written in software test cases. The software tester evaluates the design, functionality, and performance of the application by clicking through various elements. Manual testing is helpful when automated testing is not possible.
Next is Test Analysis
Software Test Analysis is the process of looking into test artifacts to base your test conditions/test cases. Hence, it is also called Software Test Basis.
The source from which you derive test information could be
- SRS (Software Requirement Specification)
- BRS (Business Requirement Specification)
- Functional Design Documents
Testers can create Test Conditions by looking into the Application Under Test or use their experience. But mostly, software test cases are derived from test artifacts.
Let’s understand Test Analysis with the help of a case study
Consider a scenario, where the client sends the following
Add search functionality to an eCommerce Store
Even though the application is yet to be developed, try and develop a few software test cases for this requirement. Pause here, do your homework and move the solution ahead:
A few test cases among the many you could have thought of are listed below
- Check the search results when no keyword is entered
- Check the search results when no corresponding product is available for the keyword searched
- Check the search results when a number of corresponding products are available for the keyword searched
Here, you look into Software Test Basis (requirement send by the client), analyze it, and convert it into Software Test Conditions.
This is what happens during the different phases of V- Model. Test Plan/Cases are created using the corresponding documents available at different phases.
What is Software Testing Pyramid?
Software Testing Pyramid is a framework that can help both developers and QAs create high-quality software products. It reduces the time required for developers to identify if a change they introduced breaks the code. It can also be helpful in building a more reliable software test suite.
Essentially, the software testing pyramid also referred to as the software test automation pyramid, lays out the types of software tests that should be included in an automated test suite. It also outlines the sequence and frequency of these tests. The whole point is to offer immediate feedback to ensure that code changes do not disrupt existing features.
This test automation pyramid operates at three levels:
- Software Unit tests
- Software Integration tests
- Software End-to-End tests
What is software automated testing?
In software automated testing, there are pre-scripted tests that run automatically. The software tests are run to compare the actual results of the software product with the expected results. The automated tests help to determine whether the application performs as expected or it does not. Automated tests come handy while performing repetitive and regression tests to ensure that an application performs correctly after new changes are implemented. Software automated tests run with the help of tools, scripts, and software to perform pre-defined actions written in the software test cases.
Automation Engine Frameworks
A software test automation framework is an integrated system that sets the rules of automation of a specific software product. This system integrates the function libraries, test data sources, object details and various reusable modules.
