Detailed Description

A suite of unit tests to show that an LP solver handles basis start correctly.

To use these tests, in file <solver>_test.cc write: INSTANTIATE_TEST_SUITE_P(<Solver>LpBasisStartTest, LpBasisStartTest, testing::Values(SolverType::k<Solver>));

Definition at line 29 of file lp_initial_basis_tests.h.
