The Bug Life cycle is also known as a Defect Life cycle. It is a phase of a defect that occupies the different states during its lifetime. It starts when a testing device finds a new defect and ends when the testing device removes that defect and it is ensured that the defect is not replicated. It is now time to understand, through a basic diagram as shown below, the true workflow of a defect life cycle.
The programmer begins the bugs analysis process here, where possible, and works to repair it. If the programmer thinks that the defect is not sufficient, then an error depending on the particular reason may be passed to the following four states, Reject or Not, namely Duplicate. This is the first state of bug classification in the life cycle of the bugs. In the later stages of the bug life cycle validation and testing are carried out on these bugs if a new defect is discovered.
The development team is allocated a newly created fault for operating on the fault at this level. If there is still some problem with the flaw, the programmer will then be instructed to check again and the defect status will be reopened. In fact, ideally, the test cases are created before the code is written at all—or at least the test design, then the development of both the code and the test cases can happen simultaneously.
Since new software is released on very short iterations, regression testing becomes more and more important, thus automated testing becomes even more critical. In my perfect world of Agile testing, automated tests are created before the code to implement the features is actually written—truly test driven development—but, this rarely happens in reality.
What about you, the software developer? What is your role in all this testing stuff? One of the big failings of software development teams is not getting developers involved enough or taking enough ownership for, testing and the quality of their own code.
Instead, you should absolutely make it your responsibility to find and fix the bugs before your code goes into testing. The reason is fairly simple. The further along in the development of software a bug is found, the more expensive it is to fix. If you test your own code thoroughly and find a bug in that code before you check it in and hand it over to QA, you can quickly fix that bug and perhaps it costs an extra hour of time.
A development manager decides that the bug is severe enough for you to work on and the bug is assigned to you. The tester goes back and checks that the bug is actually fixed and marks the defect as resolved.
Ok, so by now, hopefully, you have a decent idea of what testing is, the purpose of testing, what kinds of testing can be done and your role in that whole process. Black-box testing sounds a whole lot like functional testing. Oh, and also the same question for regression testing versus automated testing.
Many of these testing terms are basically the same thing. Sometimes I feel like the whole testing profession feels the need to invent a bunch of terminology and add a bunch of complexity to something that is inherently simple.
To address some of the specifics. Black-box and white-box testing just refer to how the functional testing or other testing is done. Are you looking at the code to give you hints about what to test or are you treating the whole thing like a mysterious black box? For automated testing versus regression testing, again, we are dealing with a higher concept and implementation.
Regression testing is the concept. If you decide to become a tester and want to pass a job interview for a testing position, you should probably know all this stuff and be able to expound upon why exploratory testing is actually a valid way to test things and how user testing and acceptance testing are not the same things.

I know, I just talked about the most common types of software testing.
Last but not least, I wanted to give you a heads-up on Usersnap , which is a great solution for UAT testing and user testing , used by companies like Facebook, Red Hat, and Microsoft. Because I learned it the hard way. Back in my days… Quick Usersnap PSA: if you need a guide to customer feedback , skip jump and fly your way over there now! At a surface level, it can seem a bit extraneous. Impact by the severity of the problem: If you had a bug in the accounting software that caused all of the data to become corrupted every 1,th time the data was saved, that would be a huge impact, but very low frequency The reason I define software testing in this way is because—as any tester will tell you— you can never find all the bugs or defects in a piece of software and you can never test every possible input into the software.
The answer is simple. Develop a disciplined process to systematically identify, evaluate and solve software bugs. This approach can be scaled up or down depending on the size of your team. Before you read a single software bug report , you need to have specific goals to guide your work. Without clear goals, you will not be able to sort make meaningful progress.
In my opinion, undirected bug work leads to mediocre software. Consider a popular office productivity product like Microsoft Word or Microsoft Excel. These products have been refined and expanded for decades. Most users simply scratch the surface of what is possible. For example, some people use Excel as a database with tens of thousands of rows of data. Even then, few users extract the greatest possible value from Excel functions like PivotTables. What does this example mean for stopping software bugs?
If you have clear goals to guide your work, you will not fall victim to this challenge. Depending on your situation, there are two approaches to developing goals for your software development program.
First, you can derive your goals based on the organization as a whole. Second, you can adopt a bottom-up approach to develop goals based on your values and understanding of the user. Most well-managed organizations are driven by goals. For example, a start-up may be focused on achieving a certain level of product development or revenue in order to obtain funding to continue growing. The best goals are objective and easy to measure. If you are running a small company as an entrepreneur, you may need to come up with goals all on your own.
A few simple questions will give you all the material you need to develop goals. Once you have the answers to these questions, you can define your goals for addressing software bugs. For example, you may emphasize solving all bugs that relate to the purchase process. A software bug database makes it easy to obtain a clear picture of your software bugs. For the identification process to produce value, you will need to track a few key data points.
Remember software bug reports may come in automatically though a bug report, through customer service or other channels. Use the following checklist to check that your software bug reporting process captures all the data you need.
Use this list as a starting point to guide your software bug report process. You may be tempted to collect dozens or hundreds of data points to support your analysis process. Remember that collecting data for the sake of data is usually wasteful.
In my opinion, it is better to collect data on a small number of variables e. There are two broad ways to organize software bug data: manual and automated. A manual approach is helpful if you are operating at a small scale and have a limited budget. If it all possible, always look for an opportunity to use an automated software bug tracking solution. In either case, you will need to build a process to organize and report on your software bug data.
If you are starting from scratch, use these steps to track software bug data:. If you skip evaluating software bug reports, you will never make much progress.
