Although continuous testing was considered an afterthought earlier, with advanced development methods, it has become imperative for enterprises to deliver applications quickly and reduce business impacts. As per the report published by Statista, almost 31.3% of global enterprises had deployed continuous integration and deployment to their DevOps to accelerate the release cycle. This proves that enterprises are looking at continuous testing as the way forward to accelerate software delivery cycles, deliver high-quality digital experiences across all platforms, and fulfill all customer requirements. With the introduction of continuous integration and deployment, organizations will get the flexibility to integrate automated testing into the development stages, identify errors earlier in the process, and enhance the quality of each software release candidate.
Changes introduced by enterprises in the software development process, Global, 2021
This blog highlights the basics of continuous testing, its importance, best practices, and why HeadSpin is crucial for implementing continuous testing.
What is Continuous Testing?
In traditional testing methods, projects are handed off between various teams to complete their tasks. However, in this process, a lot of time is wasted in the form of feedback and handing over. The main principle in developing an effective DevOps approach is to bridge the gap between quick software delivery and trustworthy user experiences. Here comes the role of continuous testing in the software development cycles. Continuous testing plays a crucial role in the software delivery pipeline by providing instant feedback on business risks and software malfunctions. Nowadays, as businesses require quick development and delivery of software to customers, continuous testing tools are used for improving code quality, avoiding costly bottlenecks, and expediting software development processes. So, enterprises consider continuous testing as a more automated and secure way to ensure that their applications remain secure and effective in a complex, fast-paced development environment.
Major Three Components of Continuous Testing
1. Continuous Integration (CI)
Continuous integration is the process used in continuous testing to gather codes from the development team and place them into a code repository. Combining various developers’ codes into one project may create a lot of bugs. However, in continuous testing, test executions are automated whenever the code is integrated, allowing testers to identify errors and fix them quickly. Detecting errors before the product is released can save time, money, and effort for companies.
2. Continuous Delivery (CD)
Continuous delivery is an important stage in continuous testing. This process helps enterprises work on small, frequent changes or updates to their products. In the continuous delivery model, development teams will be ready with code versions during every stage of development to deploy to production.
3. Test Automation
Test automation is a major component of continuous testing. The main benefit of test automation in continuous testing is the quick feedback all the teams receive. Moreover, continuous testing tools enable development teams to receive early and constant feedback so that updates can be made far before releasing the products or features to the market.
Importance of Continuous Testing in DevOps
In the continuous testing model, QA teams use automated end-to-end testing methods that incorporate existing development processes while fixing errors and enabling continuity throughout the software development process. Let’s check the main advantages of incorporating continuous testing in DevOps.
- Reducing and amplifying the feedback cycle: With automated test cases integrated into the build pipeline, teams can gather feedback instantly for each step.
- Quality first: With continuous testing, applications are tested continuously from the start until the end. This helps development and testing teams prioritize quality in all stages.
- Maximum test coverage:Continuous testing can help QA teams to improve and increase the test coverage, as CI/CD pipeline automation testing is incorporated right from the initial stages of development.
Continuous testing also gives confidence to enterprises that code updates will have maximum impact with minimal risk to their business even before the release of their product or feature in the market.
What are the Benefits of Continuous Testing?
Continuous testing provides several benefits to growing enterprises, including the following:
1. Get Risk-based Feedback
With the support of continuous testing, QA teams can identify bugs in the code and resolve them before the release. Test automation tools help in this process with actionable insights. Automation testing is more effective than manual testing, which consumes a lot of time and misses some important defects. In the continuous testing model, test automation tools generate risk-based insights, which will help testers strengthen the coverage of business risk factors by finding as many issues as possible before the release.
2. Test with More Efficiency
Continuous testing will help development teams to decide whether shift left testing or shift right testing is necessary for the software development cycle. Another factor that improves the efficiency of software development with continuous testing is end-to-end testing. Automated end-to-end testing helps QA teams to eliminate false positives and timeouts. With the continuous testing model, enterprises can ensure that they have a robust architecture with them for the future expansion of their products or features, especially when users demand new features.
3. Improve Collaboration Between Teams
Continuous testing helps organizations to create a more efficient development pipeline by ensuring that every team works together effectively. Collaboration among various teams is very important for increasing the productivity and efficiency of the software development process. With the integration of quality assurance into all stages of the development cycle, all teams involved in the development of software products are aware of every step in the pipeline and are better able to deliver high-quality code from the early stages. Also, in the continuous testing model, development teams can ensure that high-quality code is being developed from the moment development teams start to code.
4. Make Smarter Release Decisions
The use of continuous testing in agile environments and DevOps has reduced the time required for the design, development, and delivery of software product updates. With the reduction in the time required for software releases, business risk is also increasing. A comprehensive analysis of business risks is necessary before release candidates are deployed. Again, continuous testing can be the savior for software developers by helping them to decide when and how to release changes that need to be done.
5. Deliver Better User Experiences
The main focus of using continuous testing is to make sure that errors caused due to faulty codes do not reach users and disrupt their experience. It is crucial for enterprises to ensure that there is a balance between providing new features users need and not disrupting the experience they already love. Poor user experiences can lead to a reduction in sales, poor CSAT, and a negative brand reputation. So, it is essential for companies to execute testing that ensures that every element of the user experience is accounted for and preserved.
Best Practices for Successful Continuous Testing
1. Commit to Deliver Best Quality
A continuous testing framework can become a huge success when everyone across all teams commits to delivering the best quality. All teams, including development and testing, must work in collaboration to ensure that the code is optimized for test automation. Even non-technical teams, such as stakeholders, product owners, and users, must adjust their work habits and mindsets to promote continuous testing.
2. Test at Every Stage of the Development Cycle
Testing at the early stages of the software development cycle enables companies to identify bugs earlier in the development cycle, and it is less expensive compared to fixing that same bug in production. Always try to use testing as the primary step of every process so that the code continues to operate as designed even when new updates are made.
3. Monitor the Entire Development Cycle with Analytics
Data analytics are important for understanding how tests perform and quickly identifying bottlenecks and quality issues. It also offers real-time visibility into coverage, test run times, errors, and efficiency, so development teams can detect trends and make updates to codes to enhance quality and accelerate releases.
4. Use a Testing Platform that Provides a Comprehensive Coverage
Leverage the capabilities of a testing platform to deliver better customer experiences. Leverage the capabilities of a testing platform to deliver better customer experiences. To perfect digital experiences for all customers, use a testing platform that helps development and QA teams gain the coverage and flexibility they need for perfecting digital experiences.
