|
|
// These tests are primarily here to assert that the functions are properly
|
|
// registered in the functions table, rather than to test all of the details
|
|
// of the functions. Each function should only have one or two tests here,
|
|
// since the main set of unit tests for a function should live alongside that
|

// function either in the "funcs" subdirectory here or over in the cty

// function/stdlib package.

|

// patterns that are used in real-world configurations which rely on behaviors
|

// implemented either in this lang package or in HCL itself, such as automatic
|
|
// type conversions. The function unit tests don't cover those things because
|
|
// they call directly into the functions.

//
|
|
// With that said then, this test function should contain at least one simple
|
|
// test case per function registered in the functions table (just to prove

// it really is registered correctly) and possibly a small set of additional

// functions showing real-world use-cases that rely on type conversion
