teamcity test never fails - unit-testing

Question

I am implementing a Powershell build script for teamcity to test some functionality, but cannot figure out out to report an error.
I am trying to follow this description:
https://confluence.jetbrains.com/display/TCD8/Build+Script+Interaction+with+TeamCity#BuildScriptInteractionwithTeamCity-ReportingTests
However, although the script actually results in some tests being registered, it refuses to report errors. I am now back to the basic example from the . I have the following Powershell build step (error output: error, script: source):
Write-Host("##teamcity[testStarted name='className.testName']")
Write-Host("##teamcity[testStdErr name='className.testName' out='error text']")
Write-Host("##teamcity[testFinished name='className.testName']")
Resulting build log (verbose):
[13:27:12]Step 1/5: Output to build log (Powershell)
[13:27:13][Step 1/5] ##teamcity[buildStatisticValue key='buildStageDuration:firstStepPreparation' value='156.0']
[13:27:13][Step 1/5] ##teamcity[buildStatisticValue key='buildStageDuration:buildStepRUNNER_18' value='0.0']
[13:27:13][Step 1/5] Starting: C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe -NonInteractive -ExecutionPolicy ByPass -Command - < D:\JetBrains\buildagent\temp\buildTmp\powershell6640337654487221076.ps1
[13:27:13][Step 1/5] in directory: D:\JetBrains\buildagent\work\7e3fac8e390ca38d
[13:27:13][Step 1/5] className.testName
[13:27:13][className.testName] [Test Error Output] error text
[13:27:13][Step 1/5] Process exited with code 0
[13:27:13][Step 1/5] ##teamcity[buildStatisticValue key='buildStageDuration:buildStepRUNNER_18' value='536.0']
I.e. the test is registered in teamcity as executed bit it succeeds! I would expect the test to fail, due to the 'testStdErr' output! What it the correct way to make it fail?
Thanks,
Kim

You should use the testFailed directive which is listed on the page you linked:
##teamcity[testFailed name='MyTest.test1' message='failure message' details='message and stack trace']
Or change the build failure condition settings under 'Build Failure Conditions' to fail the build if you write to stderr (edit: this is my understand of the docs anyway):
Fail build if:
[ ] an error message is logged by build runner
