Overview

Class describing a target, which is unit-test binary application.

The idea is, that there is project file, which controls the build process of unit-test application. In that project file target object is created, inherited from MxxRu::BinaryTarget. To initialize unit-test it’s required to create one more file, where target object of MxxRu::BinaryUnittestTarget class is created. For example:

File to compile unit-test.

MxxRu::setup_target(
  MxxRu::Cpp::ExeTarget.new( "test/pack/prj.rb" ) {
    ...
  }
)

File to run unit-test.

MxxRu::setup_target(
  MxxRu::BinaryUnittestTarget.new( 
    "test/pack/ut.rb",
    "test/pack/prj.rb ) )

File to use unit-test.

MxxRu::setup_target(
  MxxRu::Cpp::CompositeTarget.new( MxxRu::BUILD_ROOT ) {
    required_prj( "some/project/prj.rb" )
    required_prj( "test/pack/ut.rb" )
  }
)
