When reviewing the operators listed below, keep in mind that all of them can be negated by putting the word "Not" between "Should" and the operator.

This exception will stop the test from executing and will fail it. A user in the PowerShell Discord server recently came across some tests written for Pester v4 that they wanted to refactor for use in Pester v5. ''TestDrive:\file.txt' | Should -FileContentMatchExactly 'I am' # Test will pass'TestDrive:\file.txt' | Should -FileContentMatchExactly 'I Am' # Test will fail$Content = "I am the first line.`nI am the second line. So when any exception is thrown the assertion should fail, no matter what filter you specify. But as you’ll see in a minute, because it was built in PowerShell and is open source, a savvy tester is equally able to create integration tests with this framework as well. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.By clicking “Sign up for GitHub”, you agree to our Specifically, the first line logs that the arrays are the same when they aren't (or the test would have failed).Pester version : 4.9.0 C:\Program Files\WindowsPowerShell\Modules\Pester\4.9.0\Pester.psm1should indicate why, instead of printing two equal arrays and saying they aren't equal.This makes it difficult to debug a test in which an array evaluates to an empty element.This looks like an issue with Format-Nicely, but looking at the code it should work correctly. And the answer would be: No, not really. I fixed it now. Should Not Be) is called. The functions are also type aware so a message pointing at first different character will be produced when comparing strings.The assertion condition (the PesterBe function) remains the same for the negative and non-negative call of the assertion though, the result is simply negated when a negative assertion is used.This, in theory would mean that you can have a very rich API for assertions, but in reality parsing a vast amount of different inputs correctly, while keeping intuitive syntax is difficult to do, and so the parsing logic is kept very simple. which contain logic specific to the respective assertions.It uses the standard equality (-eq) operator of PowerShell, and returns a Boolean (true or false) result. Should is used inside It blocks of a Pester test script. Would you be willing to PR a fix for this?No time to submit a PR tonight, but the problem is in the Select:So before it gets to Format-Nicely, Select-Object removes the $null (Format-Collection, Format.psm1 line 11).I moved the select to the end of the pipeline and now it works fine locally:BTW, I also gathered evidence for my suspicion that aborting at the end of the pipeline is perf-wise equivalent:If the whole pipeline didn't abort, I'd expect the write-host to keep outputting up to 100.Successfully merging a pull request may close this issue. The ones with Exactly in name are used when the BeExactly assertion is used, and the ones with Not in name are used when a negative version the assertion (e.g. These applications had to be improved and maintained. It essentially must pass a Test-Path call.Checks to see if a file contains the specified text. Uses PowerShell's -lt operator to compare the two values.Asserts that a number (or other comparable value) is lower than, or equal to an expected value. First step, as module are loaded in memory you need to instruct PowerShell to remove the module.

And that is the last thing that happens in the The result of the call to Get-TestResult function is inspected, and if it is False a failure message is obtained. A condition is evaluated (be it some value comparison, if a file exists, or if an exception was thrown) and if the condition is not satisfied (False) an exception is thrown.When you look inside of the sources of Pester you will find a whole folder dedicated to assertions. The actual value will be captured later.When the arguments are parsed by the Parse-ShouldArgs and saved in the $parsedArgs, the Should command enters the end block.

If not, you may not test the actual version of your code.
