Interpreter Test Reference — Codeunits and Streams
These tests verify calling standard codeunits from scripts (argument passing, reference semantics, scope, and error surfacing) and the stream/blob feature set that several codeunits build on.
Codeunit Calls
| Test |
What it verifies |
CodeunitCallScriptTests |
Calling codeunit members with literal, variable, and expression arguments; a call result used inside an expression; quoted subtypes and integer parameters (Type Helper.BitwiseAnd); var-parameter write-back through the argument frame (GetHmsFromTime); and error surfacing for a bad overload and an unknown function. |
CodeunitReferenceSemanticsTests |
Codeunits are reference types: state persists across calls on the same variable, and assignment shares the instance rather than minting a fresh one (verified via Rest Client base address). (Audit spec.) |
CodeunitScopeTests |
Codeunit variables work as procedure locals and as parameters, not only as globals (Math used in both roles). (Audit spec.) |
PostingCodeunitTests |
Purch.-Post surfaces posting errors as diagnostics in statement form, and the expression form traps the error and returns false; also exercises calling run as a member even though it lexes as a keyword. (Audit spec.) |
NewStandardCodeunitTests |
Declaration smoke for No. Series, Release Sales/Purchase Document, Gen. Jnl.-Post Batch, Email, and Email Message; the release surface validates its record argument; Email.Send validates argument shape and rejects an uncreated message; and Format Address exercises both shapes — the native array[8] of Text form (fills the array) and the text/record form (returns a List of [Text]), including array-dimension validation. |
Standard Codeunit Behavior
| Test |
What it verifies |
Base64ConvertTests |
Base64 Convert: text round-trip (Hello↔SGVsbG8=), the InStream source overload, and the decode-to-OutStream overload. |
RegexCodeunitTests |
Regex: IsMatch, Replace, and Split (returning a List of [Text]); an unknown member surfaces the implementation error. |
DataCompressionTests |
Data Compression: a full zip round-trip (create → add → save → reopen → list → extract) and a gzip round-trip with the IsGzip probe. |
EnvironmentInfoCodeunitTests |
Environment Information: the script answers for IsSandbox/IsProduction/IsSaaS/IsOnPrem/GetEnvironmentName agree with the native codeunit for the current environment (spec-first). |
Streams
| Test |
What it verifies |
StreamAndTempBlobTests |
Temp Blob and streams: an OutStream/InStream write-read round-trip with HasValue/Length, the ReadText() convenience form and Eos, the JSON WriteTo/ReadFrom stream overloads, copystream between two blobs, and streams passed as procedure parameters sharing the reference. |
