What Testing Installation?
aka implementation testing Installation testing is done to check the successful installation and to ensure the software works in line with expectations. Done before the first end-user interaction with the software, installation testing is the last phase of the software life cycle testing (STLC).
Basics of Testing Implementation
Before moving forward is very important for us to know about the basic features of installation testing. Here are some important features of the test installation, that we need to know:
Software test engineer to implement before the configuration manager.
As previously stated, identifying and detecting bugs and defects in the installation process.
testing the implementation of activity-based testing.
installation testing is the last phase of STLC.

How to do the installation Testing?
It is very important to carry it out properly so it does not leave a chance for each disorder. You can ensure smooth testing with follow below given points.
Check the version of the existing software and validate if the software installer checks to them as well.
During the installation validate if the software gives users the option to specify the installation location and also offers a selection of the default location. Also, validate the software installed in the specified location.
Validation of the display according to the instructions on the installer.
Verify the software is easy to install on various locations such as the Internet, through a network, from a CD, etc.
Stop the installation process in between and check whether the system back to its original state.
Manual check disk space and then validate if the installer software calculates the exact disk space.
Reaction Validation software for low disk space. Check whether respond accurately when disk space is low.
Verify all changes to the registry during the installation process.
One of the main part of the installation testing installation testing. Validation when removing the software, the system will remove all related system files.
Today, the software is available on a variety of platforms, because it is very important to validate their proper installation on different platforms. Although time consuming, it is very important to make sure the software is easy to install on multiple platforms.
Importance of Testing Installation
Think why it is important to spend time testing the installation? installation testing plays an important role in the life cycle of software testing. Here are some reasons to prove its relevance:
Installation is the first interaction of software and your potential customers. Therefore, the installation is very important to make a good impression on your potential customers.
installation testing can help you to ensure complete coordination between the various components of your software.
Apart from installation testing, installation testing is also equally important. This ensures that all related system files removed from the system frees all the space occupied by the system memory.
Challenges in Testing Installation
installation testing have broad scope and be time-consuming; can be very challenging for you at times. Some of the common challenges that can apply are:

Installation test cases need to be run in a variety of environments with different configurations.
They need to be run in a variety of system conditions.
It gets time-consuming to run several test cases on different systems with different configurations.
There is no clear model of tests, tools and criteria for testing the installation of test coverage that can further increase the challenge.
The general case in Test Installation Test
Test Case is very important when testing software. Similarly, the test installation as well. Here are some common test cases that can help you prepare your set of test cases.

There should be a test case for all of the workflow based on need.
Include test cases to verify the already installed version of the product and to verify to verify the path of the newer version.
Test cases to validate the required disk space is very important.
Must test cases to validate all the messages that are displayed during installation.
Include test cases to check the disk space, before and after installation.
Must Test cases to compare files and packages from a previous version installed with the new version installed.
Validating the registry changes are important inclusions.
Forced stop of installation is another aspect that needs to be examined.
Include custom test cases to validate the installation and the default installation path.
Do not forget to include test cases to test memory is not enough and not enough disk space.
Must test cases to check the installation process while the high security and firewall ON.
Include test cases to test the time required for installation.
Including test cases for testing a successful installation
