Upgrade Testing Framework to support dlopen & all documentation

[Ulrond]

Subject

Goal

• Building the headers, including the testing suites and allow a currently unsupported function to be defined via stubs.

  • So that the testing suites can be written to the stubs, which will fail but will build.
  • Then the implementors of the new functions have a testing suite they can use to compare against implementation.

• Upgrade the makefiles to build WEAK_SKELETON_SRC as a list of weak skeletons srcs that will be build into the main testing app, as real weak functions

• Upgrade the makefile in the templates to support this

• Upgrade the testing suites to test this

• Upgrade the templates to also use dlopen as an example of how to remove the build time dependancy, and introduce a runtime dependancy.

• Add a switch to disable the binary loading, and swap back to weak functions (by default the DLOpen will be used).

• Add an option to if the library is not found, then use the weak functions, and display a warning? (Also a switch)

• https://github.com/rdkcentral/ut-core/wiki/4.0.1:-Standards:-Dynamic-Library-Search-Order

  • Be aware that LD_LIBRARY_PATH should likely be used, because hardcoding the default paths may not be a good idea, considering the vendors are running the testing suites against their build system, and rootfs
  • Consider displaying the paths that your using to make it clear which libraries are being found.

Requirements

• Upgrade the testing suites to support the new dlopen model
• Upgrade all the testing suites makefiles to support the new model
• Upgrade all the documentation to support the new model
• Upgrade the checking scripts for missing functions, to ignore weak functions (New task)

Include the SKELETON_SRC as part of the ut-core build in both linux + arm building.
May need to separate as a SKELETON_SRC
