Components of a Defect Management Software

 Since software developers and testers work together in the Agile and DevOps environments, it gets challenging to cope up with the increasing competition. Development teams work in collaboration with various stakeholders to make the most of the testing efforts. Defects in software applications are a norm, the sooner you realize that better it is. It is impossible to have a 100% defect/error-free software application, but experts work to make the most of their efforts. The current need for faster delivery and quality products calls for robust software testing solutions that can meet customer expectations.

A defect management system is a defect repository where all the defects appearing in a system are identified, recorded and assigned for rectification. This system includes defect management software and defect management tools to achieve projects efficiently. 

How Does Defect Management Work?

A defect management system works in a systematic manner, and records all the defects in the system without duplicating defects, and maintaining a log for future use too. There are different steps involved in the defect management that are explained below”

Identification – First of all, testers identify the defects

Categorize – When it is reported, it is automatically assigned to a team member to assess whether to rectify the defect or leave it

Prioritize – The next step is to prioritize by assessing the severity of defect and its impact on the user. The prioritized defects are handled by a formal change control board. 

Assigning Defects – After   the defects, they are then assigned to developers or testers accordingly 

Resolving Defects – The develope resolves the defect and follows the process to move further in the defect management process

Verification – The software testing team verifies the environment in which the defect was found

Closure – Close the defects after completion

Reporting – Reports are then provided to the relevant stakeholders regularly. They can also be demanded according to requirements. 

The entire process sounds pretty simple and easy, although it is not so. Defect management is tricky but using the right type of defect management software and tools helps in achieving the desired results. These tools are also integrated with other software testing tools to enhance and align all the processes between testers, developers and other relevant stakeholders. It aids all experts and specialists in planning, building and developing a quality software product. Business analysts, product managers, developers, project managers, testers. etc. is operating in a single system by sharing the same information. Defect management tools are also integrated with the test management system, which helps testing teams to share the project status with other key stakeholders. 

All these stages of defect management process contribute to a defect management software. Generally, defects are always considered negative, which may not be the case in all instances. Sometimes a tester makes a mistake while recording the defect, which can affect the entire process. So we can’t truly say that a defect management software or tool alone is responsible for effective defect management, it is also important to handle the defects efficiently.

What can you learn from the defects you found?

The bugs we find during testing can tell us a lot about the application, the state of its quality and its release-readiness. Bugs can also provide insights into our development processes and practices — and lapses therein.

How can we study bugs to improve the overall state of our project? In my article published @Gurock TestRail blog, I have described three things to learn from the bugs you find. https://blog.gurock.com/three-learn-bugs/

 The location of defect clusters

Defect clustering is one of the seven principles of software testing, and keeping an eye out for these clusters is the responsibility of a good tester.

As we log defects into a tracking tool or portal, teams generally follow the practice of measuring relevant modules, components or functional areas against each defect. When tracked over time, this information can be real gold! It helps us track which areas of the application are having more bugs.

We can plot these area metrics against the number of defects raised and find the defect rates over time. We can also create filters to raise concerns whenever the defect rates go over a certain limit in any specific area or component. This can help us combat defect clustering by doing a fresh analysis, revisiting the tests being performed and focusing more of our exploratory test efforts in those areas.

Overall, knowing about these defect clusters, keeping an eye out for them and regularly revisiting the areas will help us keep the quality of the entire system in check.

Frequency of defects (and their resolution)

The frequency of defects being found and logged tells us a lot about the maturity of the product.

In the beginning of construction sprints, defects are supposed to be frequent and plentiful. We may not go by numbers here, but the relativity of them. As we progress toward a release, the number of defects generally declines, indicating that the system is now more mature and sturdier after withstanding multiple test cycles. Some teams even use the metric of mean time between failures as an exit criterion for testing, indicating that they will only finish testing once they cannot find any new defect for a certain number of days.

As defects are raised, triaged, resolved and verified, there is a typical turnaround time that we expect. Most defects will go through this lifecycle within a reasonable stipulated time or will be postponed with a reason or business decision. Some defects may linger in the system for longer.

There may be a variety of reasons for these decisions:

  • A defect requires more information, and the developer is awaiting confirmation or details from the tester who raised it
  • The defect was misunderstood and there are comments going back and forth between the tester and developer about the expected behavior
  • The assigned developer was on vacation for a week and the defects have not been fixed, leading to a plateau in the defect-fix-rate graph
  • Defects are awaiting triage by the product owner and do not have priorities or the correct people assigned to them

Whatever the reason, knowing the cause of defects remaining open, in progress or unresolved for longer than a stipulated time is important. We may have to fix people issues or communication gaps, or may just need to schedule a short triage or discussion with the team to decide on the fate of such issues. But understanding any delays gives us a much-needed insight into team dynamics and helps us smooth out the process.

The reasons behind rejected defects

The number and type of defects getting rejected — and the reasons behind the rejections — can also tell us a lot about the state of the product and psychology of the team. If you see a high number of irreproducible defects, it may mean that some data or information is getting lost when reporting, or that the testers do not have enough time or perspective to reproduce the defects.

A high number of duplicate bugs may show that testers are unaware of the system’s history, or maybe they are new to the team and need to get a little more background. It may also be a case of the same bugs reoccurring, which might have been fixed and closed in previous releases.

Incorrect defects marked with “Not a bug” or “Working as designed” tell us about a lack of understanding of the system on the testers’ side. Or it may be due to a lack of communication among the team members, leading to different perceptions about the features that were designed or implemented.

Our findings from these types of defects can help test managers or project owners plan measures like internal trainings and knowledge sharing, which can enhance communication among team members and introduce prerequisites to fulfill before logging any issues.

There is a world of information that your defects can provide. If you take a good look at your bugs and talk about them as a team, you can find ways to use that information to your advantage.

Prevention is the Best Cure- for Defects in Agile

The agile methodology focuses on building in quality from the very beginning of the software lifecycle. That is why we aim to find and fix defects early on: A defect found and fixed in an earlier lifecycle phase is a multitude cheaper than the same defect at a later stage.

But how can we more easily make it possible to prevent defects from percolating deeper in the software development lifecycle by fixing them in their nascent stages?

This is the main theme of my latest article for @Gurock TestRail blog – where I explore and explain ways to foresee, analyze and thwart defects in an agile context.

The main points discussed are-

Communication

Conduct Reviews

Demonstrate Often

Static Analysis and CI

The 12 Agile Principles: What We Hear vs. What They Actually Mean

The Agile Manifesto gives us 12 principles to abide by in order to implement agility in our processes. These principles are the golden rules to refer to when we’re looking for the right agile mindset. But are we getting the right meaning out of them?

In my latest article for Gurock TestRail blog, I examine what we mistakenly hear when we’re told the 12 principles, what pain points the agile team face due to these misunderstandings, and what each principle truly means.

 

Principle 1: Our Highest Priority is to Satisfy the Customer Through Early and Continuous Delivery of Valuable Software

What we hear: Let’s have frequent releases to show the customer our agility, and if they don’t like the product, we can redo it.

The team’s pain points: Planning frequent releases that aren’t thought out well increases repetitive testing, reduces quality and gives more chances for defect leakage.

What it really means: Agile requires us to focus on quick and continuous delivery of useful software to customers in order to accelerate their time to market.

Principle 2:

Optimize Your Hardening Sprint for a Quality Advantage

A hardening sprint is an additional sprint that some teams run to stabilize the code and ensure that everything is ready just before release. Agile teams vary in their opinions on using hardening sprints in Scrum, but if your team does agree on having one before your release, there may be a lot to be done and varied expectations from the product owner, testers and developers. It may also lead to other work being delayed, leading to accumulation of technical debt.

In my article for Gurock TestRail Blog, I have discussed some tips on optimising the hardening sprint and achieving the maximum quality before release.

I talk in detail about some main points to focus on–

  • Plan Ahead
  • Perform End-to-End Testing
  • Perform Non-Functional Testing
  • Perform Tests on Other Platforms and Languages
  • Reduce Lower Priority Defect Counts
  • Use your sprint Wisely

Pesticide Paradox in Software Testing

Pests and Bugs sound alike?? They act alike too!! 

Boris Beizer, in his book Software Testing Techniques (1990) coined the term pesticide paradox to describe the phenomenon that the more you test software, the more immune it becomes to your tests.

Just like, if you keep applying the same pesticide, the insects eventually build up resistance and the pesticide no longer works. Software undergoing the same repetitive tests build resistance to them, and they fail to catch more defects after that.

  • Software undergoing the same repetitive tests eventually builds up resistance to them.
  • As you run your tests multiple times, they stop being effective in catching bugs.
  • Moreover, part of the new defects introduced into the system will not be caught by your existing tests and will be released onto the field.

Solution: Refurnish and Revise Test Materials regularly

In order to overcome the pesticide paradox, testers must regularly develop newer tests exercising the various parts of the system and their inter-connections to find additional defects.

Also, testers cannot forever rely on existing test techniques or methods and must be on the look out to continually improve upon existing methods to make testing more effective.

It is suggested to keep revisiting the test cases regularly and revising them. Though agile teams provide little spare time for such activities, but the testing team is bound to keep planning these exercises within the team in order to keep the best performance coming. A few ideas to achieve this:

  • Brainstorming sessions – to think of more ideas around the same component testing
  • Buddy Reviews – New joinees to the team are encouraged to give their fresh perspective to the existing test scenarios for the product, which might get some new cases added.
  • Strike out older tests on functionalities that are changed / removed
  • Build new tests from scratch if a major change is made in a component – to open a fresh perspective
