What test scenarios will you use to verify the application installation?

Application installation testing includes the following scenarios:

• Successful installation:

  • Installation with correct user permissions.
  • Installation to the default path.
  • Installation to a user-defined path.
  • Installation on a disk with sufficient free space.
  • Installation with internet connection (if required).

• Installation with errors:

  • Attempting installation without sufficient administrator rights.
  • Attempting installation on a disk with insufficient free space.
  • Attempting installation without necessary software (e.g., .NET Framework, Java).
  • Attempting installation with incorrect command line parameters (for silent installation).
  • Attempting installation with a network connection interruption (if the installer requires online access).
  • Attempting installation on an incompatible OS or architecture.

• Update (Upgrade):

  • Updating from a previous version (major releases, minor updates, patches).
  • Updating while preserving user settings.
  • Updating with rollback to a previous version (if such a feature exists).
  • Attempting update from an incompatible version.

• Uninstallation:

  • Complete removal of the application.
  • Removal while preserving configuration files (if such an option exists).
  • Checking for residual files and registry entries after removal.
  • Checking removal of shortcuts and menu items.
  • Attempting removal while the application is running.
  • Attempting removal without sufficient user rights.

• Installation under specific conditions:

  • Silent (quiet) installation from the command line.
  • Installation via group policies (in a corporate environment).
  • Installation on a virtual machine.
  • Installation on a server OS.

In each scenario, the following are checked:

• Launching the installer.
• Correct display of installation steps (license agreement, path selection, components).
• Absence of errors during installation.
• Correct creation of files, folders, shortcuts, registry entries.
• Application operability after installation (launch, basic functions).
• Correctness of error messages in incorrect scenarios.
