The reason why it is considered to be the most important type of testing in the software life cycle is that the installation process is the first interaction between the user and the software, which simple means that the process should be satisfactory. Successful installation process leads to happy customers which further increases the software installation rate and its success rate.
When do we perform Installation Testing?
- Software version has been upgraded or downgraded
- Re-installed an application to remove the encountered problems
- A new application is launched that is related to a family of applications
Types of Installation
Clean: This is the installation where the application is being installed for the first time and old version has never been installed on the system before.
Silent: This type of installation shows no messages on console during its installation process. Messages related to installation get saved in a log file.
