5 min readIn pytest, you can skip tests based on a condition by using the skipif decorator. This decorator takes a condition as an argument and skips the test if the condition evaluates to True. You can use any valid Python expression as the condition.For example, if you only want to run a test on certain operating systems, you can use the platform module to check the current operating system and skip the test if it doesn't match: import platform import pytest @pytest.mark.skipif(platform.system() .

6 min readIn pytest, tests can be executed from inside a class by using the pytest.mark.parametrize decorator to mark the test function with specific parameters. This allows for multiple test cases to be run using the same test function. Additionally, test functions within a class can be marked with the @pytest.mark.parametrize decorator to run multiple test cases with different parameters. Finally, the pytest fixture decorator can be used to set up and tear down any necessary resources for the test.

6 min readTo inject pygame events from pytest, you can create a custom pytest fixture that simulates the desired events. This fixture can be used in your test functions to inject events such as key presses, mouse clicks, and joystick movements.First, you will need to import the necessary modules for pytest and pygame in your test file. Then, define a fixture that initializes the pygame event queue and generates custom events using pygame.event.post().

5 min readIn pytest, you can assert elements of lists by using the assert keyword followed by the list indexing. For example, if you have a list called my_list = [1, 2, 3], you can assert the first element by using assert my_list[0] == 1. This will check if the first element of the list is equal to 1. You can also use list slicing to assert a range of elements in a list.

6 min readTo pass a parameter to a pytest fixture, you can declare the fixture with a parameter in its definition. When you use the fixture in a test function, you can specify the value for the parameter. This allows you to customize the behavior of the fixture for different test scenarios. Additionally, you can use fixture factories to dynamically create fixtures with different parameter values.

4 min readTo read an XML node text with spaces using PowerShell, you can use the Select-Xml cmdlet to select the specific node and then access its InnerText property to get the text value, even if it contains spaces. Use the following code snippet as an example: $xml = [xml](Get-Content "path/to/xmlfile.xml") $node = Select-Xml -Xml $xml -XPath "//node/with/spaces" $nodeValue = $node.Node.
-
6 min readTo export output from PowerShell to a CSV file, you can use the Export-CSV cmdlet. This cmdlet allows you to create a CSV file containing the output of a command or script. You can pipe the output of a command to Export-CSV and specify the file path where you want to save the CSV file. This way, you can easily store the output of PowerShell commands in a format that can be easily shared and analyzed in other applications.

4 min readTo copy folder structure only with PowerShell, you can use the following command: Get-ChildItem -Path "source_folder_path" -Recurse | Where-Object { $_.PSIsContainer } | foreach { $_.FullName.Replace("source_folder_path", "destination_folder_path") } Replace "source_folder_path" with the path of the folder you want to copy and "destination_folder_path" with the path of the destination folder where you want to copy the folder structure.

5 min readYou can execute a multi-line PowerShell script using Java by first creating a ProcessBuilder object and setting the command to "powershell.exe". Then, you can pass the script as a parameter to the ProcessBuilder object using the command line arguments. Make sure to include the "-Command" flag before the script to indicate that it is a PowerShell command. Finally, start the process and read the output if needed.
-
4 min readIn PowerShell, environment variables can be accessed through the $env: prefix followed by the name of the variable. When dealing with environment variable types in PowerShell, it is important to remember that all variable values are inherently stored as strings. This means that if you need to use an environment variable as a specific type (e.g. integer, boolean), you will need to explicitly cast or convert the value to the desired type.
-
5 min readTo split on the first occurrence using regex in PowerShell, you can use the -split operator along with a regular expression pattern that matches the first occurrence. For example, if you want to split a string $input on the first comma ,, you can do it like this: $input = "first,second,third" $parts = $input -split ",(?=.*?,)" In this example, the regex pattern ",(?=.*?,)" matches the first comma , in the string without consuming any characters after it. The (?=.*.

4 min readTo find the sum of two columns in PowerShell, you can use the Measure-Object cmdlet.First, import the data from the columns using Import-Csv or Get-Content, then select the two columns you want to find the sum of using Select-Object.Next, pipe the output to the Measure-Object cmdlet with the -Sum parameter to calculate the sum of the selected columns.
