Using native Ada statements

Component Testing for Ada

In some cases, it can be necessary to include portions of Ada native code inside a .ptu test script. You can use the #, @, and ! prefixes to do this.

Analyzed native code - #

When lines are prefixed with the # character, the Test Script Compiler analyzes the line and then copies the line into the generated code. You can use the # prefix to declare test script variables and to include the files that declare the functions under test.

Variable declarations must be placed outside of Ada test script blocks preferably at the beginning of scenarios and procedures.

Ignored native code - @

When lines are prefixed with the @ character, the Test Script Compiler only copies the line into the test harness and does not analyze the line. You can use the @ prefix to copy instructions into the test harness, when the test script compiler would not understand these instructions. Assembly instructions are examples of these instructions.

Parsed native code - !

When lines are prefixed with the ! character, the Test Script Compiler analyzes the lines, but does not copy the lines into the test harness. You can use the ! prefix to declare variables and types that are built into the compiler.
