Digital technology and Open Source platforms are sweeping the digital and disruptive technology world, and to stay up with the pace of competition, enterprises must constantly thrive to work and embrace Agile and DevOps environments with continuous improvements.
In today’s world, enterprises are catering towards and counting on next-generation technologies like AI/ML, Cloud, Mobility, etc. this is often likely to cause:
- Increased defects leakage into the assembly environment
- Reduced test cycle time for defect fix and release updates
Lately, enterprises are required to support multiple releases during a short period of their time with both minor and major changes to sustain fierce competition, which needs them to continuously validate releases comprehensively across all platforms, which may be very expensive and time-consuming if not done correctly.
This is where DevTestOps (DTO) steps in ensuring the QA process starts before the primary developer within the team begins to write down code and it continues throughout the lifetime of the software.
DTO is an engineering methodology, which needs a software application to be developed consistent with DevOps principles and a ‘Fail First’ approach wherein all stakeholders are united on a standard set of quality standards, best practices, and business outcomes.
Journey Towards DevTestOps with Continuous Quality Engineering
A methodical approach is required to implement Continuous Quality Engineering (CQE) and acquire fast and continuous feedback on the standard of software products via end-to-end test automation. additionally, there must be clearly established quality check gates within the QE cycle with comprehensive metrics on application development efficiency.
Enterprises got to transform themselves with reference to their business model, operational mechanisms, functionalities & technologies. TestUnity recommends the below-mentioned BOFT Transformation Methodology for enterprises to enable a smooth transition from their existing QA into CQE during a step by step process:
- B – Business Transformation
- O– Operational Transformation
- F – Functional Transformation
- T – Technological Transformation
The above-mentioned BOFT methodology must be combined with Dual Shift (Combination of Shift Left and Shift Right mechanisms) test methodology to make sure that there’s continuous improvement and innovation within the business.
As a part of Shift Left, the QE team is involved right from the ideation phase and continuously tests the merchandise features. As a part of Shift Right, the QE team is involved from the inception of the assembly release and continually monitors the appliance to supply recommendations and continuous quality improvements.
In Shift Left, the QE team closely works with Dev and merges into the feature team to know the essential functionality of the feature event before the event of a selected feature.
QE feature team must come up with optimized test cases with risk-based and model-based testing and TDD-based unit test cases alongside the Dev team.
Once the build is deployed within the staging environment, there must be a fast code review analysis and execute automated TDD UNIT scripts with the fail first strategy, followed by a smoke test.
By the time build is deployed into QA Environment for testing, the bulk of the P1 and P2 defects are within the fixing stage and therefore the business is conscious of the build quality.
Once the build is deployed, Shift Right is triggered into the assembly environment and there must be continuous monitoring by the QE team who conducts Adhoc exploratory & usability tests to supply continuous feedback to the Dev team.T
Based on the QE team feedback, the code is defined by the event and this is often an infinite continuous improvement and integration cycle as mentioned within the given image.
Listed below are few highlights and best practices of DTO:
- Test-Driven Lighthouse Delivery Model with Distributed Testing
- Fail-Fast Strategy
- Hyper Automated Testing
- Open Source Technology Adoption
- Code Scanning
- API Driven Testing
- Gatekeeper Strategies
To establish a flawless DevTestOps environment, the QE team must closely work and collaborate with the Dev team and seek support on continuous release & deployment through DevOps practice and continuously monitor production applications for improvement and innovation.
