As you're basically testing libsolv, you might as well use libsolv's
testcase support. Your first test is:

repo system 0 testtags <inline>
repo repo1 0 testtags <inline>
#>=Pkg: TestA 1 1 noarch
#>=Req: TestB | TestC
#>=Pkg: TestB 1 1 noarch
#>=Pkg: TestC 1 1 noarch
system x86_64 rpm system
poolflags implicitobsoleteusescolors
job install name TestA
result transaction,problems <inline>
#>install TestA-1-1.noarch at repo1
#>install TestC-1-1.noarch at repo1

The second one (that fails) is:

repo system 0 testtags <inline>
#>=Pkg: TestB 1 1 noarch
repo repo1 0 testtags <inline>
#>=Pkg: TestA 1 1 noarch
#>=Req: TestB | TestC
#>=Pkg: TestB 1 1 noarch
#>=Pkg: TestC 1 1 noarch
system x86_64 rpm system
poolflags implicitobsoleteusescolors
job install name TestA
result transaction,problems <inline>
#>install TestA-1-1.noarch at repo1

I.e. "TestB" was also added to the installed repo section.

$ ./testsolv test2.t
Results differ:
+install TestC-1-1.noarch at repo1

Note that it no longer fails if you add a
    solverflags ignorerecommended
line.

Cheers,
  Michael.
