Tests

Stack​

The test project (Tests/MCIBr.Tests/) uses:

  • xUnit
  • Microsoft.NET.Test.Sdk
  • coverlet.collector

See Tests/MCIBr.Tests/MCIBr.Tests.csproj.

What tests guarantee (concrete examples)​

Rounding/truncation and helpers​

File: Tests/MCIBr.Tests/UtilsTests.cs

  • Ensures ResolveValue(..., CalcType.Round, decimals) works for positive, zero, and negative decimals
  • Ensures ResolveValue(..., CalcType.Truncate, decimals) works for decimals in 0..4
  • Ensures IfThen.Condition(condition, whenTrue, whenFalse)

RT effective dates (dates and override)​

File: Tests/MCIBr.Tests/VigenciaTests.cs

  • Ensures behavior around CBS/IS start date (2027-01-01)
  • Ensures overriding the date changes the effective-date results
  • Ensures transition from ICMS/PIS/COFINS to IBS starting at 2033-01-01

Tax coverage (by file)​

Beyond the examples above, there are multiple tests focused on ICMS/ICMS-ST/DIFAL/FCP scenarios, organized by CST/CSOSN, for example:

  • Csosn101IcmsTests.cs
  • Csosn201IcmsStTests.cs
  • Cst00IcmsTests.cs
  • Cst10IcmsStTests.cs

Interpret “expected behavior” strictly from what tests assert (Arrange/Act/Assert) in each file.
