| Name| Description
| xref:BloombergLP/bsls/BslTestUtil/callDebugprint.adoc[`callDebugprint`] 
| Print the value of the specified `object` of the parameterized `TYPE` to the console. Optionally specify a `leadingString`, which will be printed before `object`, and a `trailingString`, which will be printed after `object`. If `leadingString` is 0, then nothing will be printed before `object`. If `trailingString` is 0, then nothing will be printed after `object`.
| xref:BloombergLP/bsls/BslTestUtil/flush.adoc[`flush`] 
| Write any unwritten text in the output buffer to `stdout`.
| xref:BloombergLP/bsls/BslTestUtil/makeFunctionCallNonInline.adoc[`makeFunctionCallNonInline`] 
| Return the specified `functionPtr` (expected to be a static function pointer) without modification. The value of `functionPtr` is transformed through `identityPtr` so that if the caller is in a different module, the compiler will have no way of knowing that this is an identity transform and thus no way of inlining the call.
| xref:BloombergLP/bsls/BslTestUtil/printStringNoFlush.adoc[`printStringNoFlush`] 
| Print to the console the specified string, `s`. Note that the underlying stream is _not_ flushed.
| xref:BloombergLP/bsls/BslTestUtil/printTab.adoc[`printTab`] 
| Print to the console a tab character, and then `flush` the underlying stream to ensure the text is written.
