Test Failure Investigation

• Read test file and implementation to understand failure
• Identify root cause of Expected 1, but got $null
• Verify fix was applied

Root Cause

The test failure was caused by using incorrect $TestConfig property names. The originally generated test code used $TestConfig.instance2 (which doesn't exist in TestConfig), then a first fix attempt used $TestConfig.SingleInstance (also wrong). The correct property is $TestConfig.InstanceSingle.

Why the specific error occurred:

1. New-DbaDatabase -SqlInstance $null — with an undefined property, the SqlInstance was $null
2. The BeforeAll setup failed silently or the extended properties were never created
3. Get-DbaDbDataClassification returned $null (no classifications found)
4. In Pester v5, $null | Should -Not -BeNullOrEmpty passes when $null is piped (quirky behaviour)
5. $null.Count | Should -Be 1 → "Expected 1, but got $null" ✓

Already Fixed

You already resolved this in your two fix tests commits:

• e310ad3 — changed instance2 → SingleInstance (still wrong)
• ad2c38a — changed SingleInstance → InstanceSingle (correct ✓)

All three test files now use $TestConfig.InstanceSingle. The removal of -Confirm:$false from test calls is also correct — $TestConfig.Defaults already sets '*-Dba*:Confirm' = $false globally for all tests.

No Further Changes Needed

The fix is correct. The tests should pass once run against a live SQL Server instance.

The result has one element and is not an array, so testing for Count beeing 1 is not correct. Testing for not null is enought.

Very nice, even takes care of the sql server minimum version, thank you 🙏🏼
