How do you find the root cause of a bug?

Start with your problem description and ask multiple times “Why?” to figure out the cause for each problem. The basic theory behind this is that every cause has an effect. Here, the visible effect is the bug you want to fix. For difficult bugs, the root cause is likely hidden behind another cause.

Which of these is the first thing to do when you find a bug in the software?

1) Report the problem as early as possible: While testing if you observed any bug, add this bug to the bug defect tracking tool immediately, don’t wait to write bug in details afterward. If you thinking of reporting bug later then it might be possible that miss few important reproduce steps.

How do you do simple root cause analysis?

To do a root cause analysis the right way, you should follow four basic steps.

1. Step 1: Define the problem. Start with the obvious: What is the problem?
2. Step 2: Collect the data. Collect all available data related to the incident.
3. Step 3: Map out the events.
4. Step 4: Solve the root of the problem.

What should you do if you determine the root cause and find that it is out of your control?

What should you do if you determine the root cause and find that it is out of your control? Nothing. Once you determine the root cause, your work is done whether it is in your control or not.

What should be done after a defect is found?

found, a tester is required to submit a bug report. Hence, a bug report should be well documented. Make it easy and clear to let the developer know the exact failure of the software.

When should you fix bugs?

In its most brutal form, Fix Bugs First means that development of new features should stop immediately when a bug is discovered. The team must then take care of known bugs before adding complexity to the software. As a result quality of existing features increases.

How do you handle bugs in code?

In this article, I will share some strategies for achieving this.

1. Don’t Write Them. The absolutely best way to deal with bugs is not to write them in the first place.
2. Don’t Fix Them.
3. Use an Issue Tracker.
4. Gather All the Information.
5. Write Down Your Assumptions.
6. Narrow Down the Problem.
7. Re-think Your Architecture.
8. Ask For Help.
