Finding a BUG in an APP is very important thing, Right? If you are a software tester or a QA engineer then you must be thinking every minute to find a bug in an application. And you should be!

I think finding a blocker bug like any system crash is often rewarding! No I don’t think like that. You should try to find out the bugs that are most difficult to find and those always misleads users.

Finding such a subtle bugs is most challenging work and it gives you satisfaction of your work.

For Instance, “There was a cron (cron is a automated script that runs after specified time or condition) to process the log files and update the database. Such multiple crons are running on log files and DB to synchronize the total data. There were two crons running on one table with some time intervals. There was a column in table that was getting overwritten by other cron making some data inconsistency. It will take a long time to figure out the problem due to the vast DB processes and different crons.”

Point is try to find out the hidden bugs in the system that might occur for special conditions and causes strong impact on the system. You can find such a bugs with some tips and tricks.

So what are those tips:

1. Understand the whole application or module in depth before starting the testing.

2. Prepare good test cases before start to testing. I mean give stress on the functional test cases which includes major risk of the application.

3. Create a sufficient test data before tests, this data set include the test case conditions and also the database records if you are going to test DB related application.

4. Perform repeated tests with different test environment.

5. Try to find out the result pattern and then compare your results with those patterns.

6. When you think that you have completed most of the test conditions and when you think you are tired somewhat then do some monkey testing.

7. Use your previous test data pattern to analyse the current set of tests.

8. Try some standard test cases for which you found the bugs in some different application. Like if you are testing input text box try inserting some html tags as the inputs and see the output on display page.

9. Last and the best trick is try very hard to find the bug .  As if you are testing only to break the application!

Follow these Tips and DeBUG your app…

Top 10 FREE Data Recovery Software

In my experience, accidentally deleting important files or forgetting to backup important files before formatting are quite often. At first when i lost my data in a External Hard-drive crash i didn’t know how to restore my data. But recently i came across these bunch of free softwares which can restore data from crashed HDD and flash drives.

STEPS To follow

When recovering data from accidental deletion, there are some rules to follow.
1. Stop using the hard drive you want to recover as main hard drive (Windows has disk and registry activity in background. Don’t believe? Run RegMon, FileMon and DiskMon)
2. Do not install the data recovery software on the hard drive that you want to recover.
3. Do not save the recovered files on the hard drive that you’re recovering.

Do take note that these are my top 10 picks for FREE data recovery software. Number 1 does not mean it is better than number 5.
