.SH NAME
Test::use::ok \- Alternative to Test::More::use_ok
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\&    use ok \*(AqSome::Module\*(Aq;
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
According to the \fBTest::More\fR documentation, it is recommended to run
\&\f(CWuse_ok()\fR inside a \f(CW\*(C`BEGIN\*(C'\fR block, so functions are exported at
compile\-time and prototypes are properly honored.
.PP
That is, instead of writing this:
.PP
.Vb 2
\&    use_ok( \*(AqSome::Module\*(Aq );
\&    use_ok( \*(AqOther::Module\*(Aq );
.Ve
.PP
One should write this:
.PP
.Vb 2
\&    BEGIN { use_ok( \*(AqSome::Module\*(Aq ); }
\&    BEGIN { use_ok( \*(AqOther::Module\*(Aq ); }
.Ve
.PP
However, people often either forget to add \f(CW\*(C`BEGIN\*(C'\fR, or mistakenly group
\&\f(CW\*(C`use_ok\*(C'\fR with other tests in a single \f(CW\*(C`BEGIN\*(C'\fR block, which can create subtle
differences in execution order.
.PP
With this module, simply change all \f(CW\*(C`use_ok\*(C'\fR in test scripts to \f(CW\*(C`use ok\*(C'\fR,
and they will be executed at \f(CW\*(C`BEGIN\*(C'\fR time.  The explicit space after \f(CW\*(C`use\*(C'\fR
makes it clear that this is a single compile\-time action.
