What is Software Testing?
The software testing definition connotes the process of verifying whether the final software solution resembles the anticipated outcomes. Software testing assists in distinguishing bugs/errors or gaps in the coding as well as any conflict in the set of requirements provided by the client. Moreover, the software testing services also warrant that the software system is error-free.
How Does Software Testing Benefit Businesses?
Software testing is extremely beneficial for the successful deployment of software. The following are the most vital advantages of performing software testing:
1. Saves Money:
Some businesses believe investing in software testing is costlier, however, in the long run, it actually saves a substantial amount for the business. Deploying a faulty software will not only cost you but also your clients a lot of money. An undetected bug during the later stages of the development process is ideally more difficult and expensive to resolve. An undetected bug during the later stages of the development process is ideally more difficult and expensive to resolve.
2. Prevents Calamities:
Defects in software designed for emergency purposes or having crucial functions such as emergency alerts or monetary transactions can have disastrous effects. Communication breakdown, loss of data, or system blackouts can lead to complete system failure. Software testing solutions resolve these issues in the initial development phase which helps businesses avoid catastrophes.
3. Builds Reputation:
An error-free software will gain more praise from its clients and users. Clients are more likely to trust a business that delivers a bug-free software. This can only be achieved with the assistance of top software testing service companies. Moreover, automated software testing can also help build long-term relationships with the clientele, while boosting revenue.
4. Offers Customer Satisfaction:
As mentioned above, clients rely more on companies that offer problem-free software. Simultaneously, a software that has a smooth operation and does not glitch provides unmatched client satisfaction. Moreover, for any company, delivering exceptional user experience is crucial as that can make or break the product.
5. Easy Integration:
The software may not necessarily work independently. Software testing techniques can come handy in such situations in ensuring that the software seamlessly integrates with any existing program. Automated software testing can also provide detailed analysis regarding the performance of all the active systems.
Which Are the Different Software Testing Methodologies?
Software Testing Methodology is the strategy implemented to deliver a product that meets the clients’ expectations. The testing methodology defines the objective of the test, its strategies, and deliverables. The testing models are somewhat similar to software development structures.
The most popular testing methodologies are the Waterfall Model, Iterative development, and Agile methodology.
1. Waterfall Model
The waterfall testing model progresses sequentially similar to the software development phase. Each phase commences only once the previous phase is finished.
This software testing model is very simple to design and handle. The testing requirements are clearly outlined beforehand, which allows easy testing of each segment of the system. However, since each phase can only begin once the previous stage is cleared, it makes it difficult for the model to accommodate unplanned events.
2. Iterative Model
In iterative software development, a larger project is subdivided into smaller parts, which are subjected to numerous iterations of the waterfall methodology. The complete system undergoes testing, with the completion of an iteration. The feedback generated from testing is subsequently incorporated into the next cycle.
The chief benefit of iterative development is that the reports from each cycle of the tests are used in the next cycle, enhancing the testing process. There is a drawback, however, as this methodology increases communication overheads.
3. Agile Methodology
In Agile methodology, the software is created in incremental, rapid cycles. Similarly, Agile testing analyses the codes after every cycle. This warrants that every bug is fixed before the next release.
This testing procedure is ideal for projects that require frequent changes or moderations. Although for the success of this testing methodology, it is crucial that there is a constant interaction between the software testers, developers, and clients.
What Are the 6 Stages of Software Testing Life cycle?
Software Testing Life Cycle (STLC) refers to the various phases of the software testing procedure. Software testing is a very significant stage in the software development life cycle (SDLC) which determines the quality of the end product. During the development stage of SDLC, the software testers analyze and establish the scope of testing. This is essential as it significantly reduces the software test cycle time. Post-testing stage, the software is then fixed for bugs and ready for deployment.
1. Requirement Analysis:
Requirement Analysis is the primary step of the Software Testing Life Cycle (STLC). This phase concentrates on understanding the requirement bar set by the client. The quality assurance team coordinates these details with the stakeholders to better assess which systems are to be tested. This stage is executed in parallel to the Requirement gathering phase of SDLC.
2. Test Planning:
Test Planning as the name suggests is crucial for formulating all testing plans. The software testers estimate the effort and cost invested in testing the project. The software test plans also classify the metrics, thereby outlining the course to gather and track those metrics.
3. Test Designing:
The next phase is test designing or test case development. In this, the software testers transcribe multiple detailed test cases. The testing team analyzes and prepares the required test data and breaks it down into numerous sub-tests to improve coverage. This step also determines the test exit criteria, highlighting when to conclude the testing.
4. Test Environment Setup:
Quality analysts set up a test environment with the intention of duplicating the end-users’ work conditions. The test environment set up includes installing a database server, front-end operating environment, client operating system, etc. Since this stage performs independently, software testing teams can establish a testing environment simultaneously with the test design phase.
5. Test Execution:
Once the testing team formulates the test designs and sets up the test environment, test execution is launched at a full pace. This phase ensures that the entry criteria of the testing module are met and each output is documented appropriately. The tests are repeated sequentially until every bug and system errors are resolved.
6. Test Closure:
This is the final stage of the software testing life cycle, which concludes the process of testing. This phase is essential since it ensures that all the open severity defects are tackled as well as all the test cases are executed deliberately. The test matrices, final test report, test closure reports, etc. are deliverables after this point.
What Are the Types of Software Testing?
There are two chief software testing types:
- Functional Testing
- Non-Functional Testing
1. Functional Testing:
Functional testing authenticates the software system against operational requirements as well as specifications. The main goal of functional testing is to verify the key operations of the system, its basic usability, and accessibility while checking for error conditions.
The four main Functional Testing categories are as follows:
1. Unit Testing: Unit Testing focuses on individual components of the software to ensure that the system functions the way it is expected. Unit tests aid software testers in fixing bugs and defects in the earlier stages of the development cycle. Hence, coders can make changes in the codes as required.
Unit testing can be automated as well as performed manually. The testers can isolate groups of code and test them rigorously. This helps in identifying unnecessary dependencies amongst the codes which should be eliminated. A vital benefit of unit testing is that it authorizes programmers to restructure existing codes to ensure the module still functions flawlessly.
2. Integration Testing: Integration testing logically assembles software modules in a group and tests them. This allows testing service providers to identify and resolve bugs hindering communication between the different software modules. Integration testing also covers the impromptu changes made in the software which might not have been unit tested.
This testing procedure mainly concentrates on the data flow between segments of software. For instance, when a user enters their login credentials and clicks on the login button, they must be directed to the main page of the software. To ensure this, integration testing analyzes the interface link between the login page and the homepage. Integration Testing can be executed via the Big Bang approach or Incremental approach.
3. System Testing: System testing validates the complete application as a whole. It ensures that the end-to-end functioning of the system meets the quality standards set by the client. System testing is generally performed by independent software testers who haven’t contributed to the development of the software in any way. This ensures that the results and reports delivered are accurate and unbiased.
Automated software testing also studies the result of every input in the system to ensure that desired outputs are achieved. Moreover, it also tests the experience of the users. Apart from the business requirements, system testing also validates the architecture of the application.
4. Acceptance Testing: Acceptance testing is also known as User Acceptance Testing (UAT), is performed to assess whether the system is ready for deployment. These tests are done by clients or end-users to ensure the integrity of the application. During software development, there are chances that certain user requirements may not be properly communicated to the developers. This may result in the development of a system that is extremely different from what the user requested.
Acceptance testing implements the following steps.
- Analysis of Client Requirements
- Distinguish Test Scenarios
- Formulating UAT Test Plans
- Run Test Cases
- Record Results
- Confirm Objectives
Once this testing procedure is completed and the system passes the tests, the program is then moved to production.
2. Non-Functional Testing:
Non-Functional Testing verifies the non-operational aspects of a software application such as performance, usability, reliability, etc. It is intended to assess the readiness of the software that is not tackled by functional testing.
For example, Non-functional testing checks the number of people who can simultaneously login to an application.
The key objectives of Non-functional testing are:
- Increase usability, maintainability, efficiency, and other criteria of the product.
- Decrease production risk and cost.
- Optimize product installation.
- Accumulate metrics for internal R&D.
The following are the different software testing types of Non-functional testing modules:
Apart from the above mentioned, testing service companies also offer Automation testing, Compatibility testing, Compliance testing, Load testing, etc.
Businesses can also opt for additional software testing tools to further improve the implemented software testing techniques. Some of the popular software testing tools are A/B testing software, QA testing software, Beta testing software, etc.
