this bit of Sed magic relies on the fact that we happen to write
the almost correct class name of a test into the header comment.
HOWTO:
for F in $(find tests -type f \( -name '*.cpp' \) -exec egrep -q '§§TODO§§' {} \; -print);
do sed -r -i -e'
2 {h;x;s/\s+(.+)\(Test\).*$/\\ref \1_test/;x};
/§§TODO§§/ {s/§§TODO§§//;G;s/\n//}'
$F;

* @test verify the simple standard usage pattern, where command arguments
|
|
* for binding are passed via UI-Bus message with GenNode elements.
|
|
* This is a simplified demonstration, but covers some tricky aspects.
|
|
* - commands may define arguments of arbitrary type, and at runtime
|
|
* these are initialised from the set of standard types allowed
|
|
* within GenNode elements. Here the Duration is initialised from
|
|
* a TimeSpan object
|
|
* - we support immutable argument types, which means the command binding
|
|
* machinery works without (re)assignment, only copy construction of
|
|
* argument holders into an inline buffer.
