Difference between Retesting and Regression testing?

Retesting	Regression
Retest is carried out when a particular defect is fixed and tester has to run through the test cases related only to the defect fixed	Regression testing is carried out to check if the defect which is fixed in the module has affected any other module or not. Here tester has to run through the whole module i.e. the test cases which are already passed too and not a particular test case.
Retest is carried out to check if the prior defect which is logged has been rectified.	Regression testing in laymen term is to check if there are any side effect to the defect fixed.
Retest is a planned testing	Regression testing is generic testing

How do you install an application without syncing your iOS device to iTunes (NOT A HACK).

Had i knew this few years back i wouldn't have pain of apps getting deleted on syncing accidentally. Normally in a medium budget company you have to share devices with your colleagues which leads to every single person syncing the same device in multiple system thereby deleting apps. Every other person in my team had suffered due to this problem. I recently got shifted to other team and a developer taught me how to install the build without syncing. It doesn't require rocket science guys, here you go.


The software you would require is Xcode (Xcode is a development tool used by developer to code and quality testing team use them for installing the build) You can download this from Mac app store.


Here is the link to Mac app store : https://itunes.apple.com/in/app/xcode/id497799835?mt=12


Steps to install application to your apple device through Xcode


- Connect you iOS device to your Mac system.
- Download the required game/application through iTunes.
- After it gets downloaded, go to library section in iTunes application and then click on the application/game you have downloaded.
- Right click and select Show in Finder option. This would open finder with your game/applications ipa file selected
- Open Xcode application and then select the device which is plugged in.
- Click on Application tab which displays different applications installed.
- Drag the ipa file to Xcode application tab.
- If the file is a bit bigger then it takes more than 5 minutes to copy the file (Wait till you see the yellow dot in Xcode)
- After it gets installed open the application in iOS device
- Installed application would ask you to enter the login credentials.
- Enter the login credentials.
Please Note: The login credential should be the same as the one from which you have downloaded the app.
- Voila! you are ready to use the application without syncing :)


Easy isn't it :) Now go try it.
