Assuming that the include requirement in the project's requirements is 
enough for building the library, the usage-requirements shouldn't be 
strictly necessary in this case (even though strongly recommended). This 
should be enough:

---
project MyProject
    : requirements <include>include
    : build-dir bin
    ;
lib MyLib1 : [ glob src/*.cpp ] ;
exe test-mylub : MyLib1 test/test-mylib.cpp ;
---
If you want to run the test executable automatically, one could use the 
unit-test rule instead:
---
import testing ;
project MyProject
    : requirements <include>include
    : build-dir bin
    ;
lib MyLib1 : [ glob src/*.cpp ] ;
unit-test test-mylib : MyLib1 test/test-mylib.cpp ;
