test function is deprecated

Example

This error occurs when a function is prefixed with test.

Erroneous code example:

test function foo() {
    // logic...
}

The compiler will reject this code with, for example...:

Error [EPAR0370016]: "test function..." is deprecated. Did you mean @test annotation?
    --> test.leo:1:1
     |
   1 | test function foo() {
     | ^^^^

Solution

The test function syntax is deprecated, but you can achieve the same result with @test function:

@test
function foo() {
    // logic...
}
