Unit test are too general

[Hordex]

Single unit test cover too much functionality, example from DynarrayTests.cpp:

TEST_CASE("Dynarray constructors", "[Dynarray]")
{
	// default constructor
	Dynarray<int> a;
	REQUIRE(a.GetSize() == 0);
	
	// initializer list constructor
	Dynarray<int> b{ 1, 2, 3 };
	REQUIRE(b.GetSize() == 3);
	REQUIRE(b[0] == 1);
	REQUIRE(b[1] == 2);
	REQUIRE(b[2] == 3);

	// reserve constructor
	Dynarray<int> c(5);
	REQUIRE(c.GetSize() == 0);
	REQUIRE(c.GetCapacity() >= 5);

	// copy constructor
	Dynarray<int> d(b);
	REQUIRE(b.GetSize() == 3);
	REQUIRE(d.GetSize() == 3);
	REQUIRE(d[0] == 1);
	REQUIRE(d[1] == 2);
	REQUIRE(d[2] == 3);

	// move constructor
	Dynarray<int> e(std::move(b));
	REQUIRE(b.GetSize() == 0);
	REQUIRE(e.GetSize() == 3);
	REQUIRE(e[0] == 1);
	REQUIRE(e[1] == 2);
	REQUIRE(e[2] == 3);
}

should be like:

TEST_CASE("Dynarray default constructor", "[Dynarray]")
{
	Dynarray<int> a;
	REQUIRE(a.GetSize() == 0);
}

TEST_CASE("Dynarray initializer list constructor", "[Dynarray]")
{
	Dynarray<int> b{ 1, 2, 3 };
	REQUIRE(b.GetSize() == 3);
	REQUIRE(b[0] == 1);
	REQUIRE(b[1] == 2);
	REQUIRE(b[2] == 3);
}

TEST_CASE("Dynarray reserve constructor", "[Dynarray]")
{
	Dynarray<int> c(5);
	REQUIRE(c.GetSize() == 0);
	REQUIRE(c.GetCapacity() >= 5);
}

TEST_CASE("Dynarray copy constructor", "[Dynarray]")
{
	Dynarray<int> b{ 1, 2, 3 };
	Dynarray<int> d(b);
	REQUIRE(b.GetSize() == 3);
	REQUIRE(d.GetSize() == 3);
	REQUIRE(d[0] == 1);
	REQUIRE(d[1] == 2);
	REQUIRE(d[2] == 3);
}

TEST_CASE("Dynarray move constructor", "[Dynarray]")
{
	Dynarray<int> b{ 1, 2, 3 };
	Dynarray<int> e(std::move(b));
	REQUIRE(b.GetSize() == 0);
	REQUIRE(e.GetSize() == 3);
	REQUIRE(e[0] == 1);
	REQUIRE(e[1] == 2);
	REQUIRE(e[2] == 3);
}

This makes adding new tests more intuitive and reading reports easier and informative. After all failing test "Dynarray copy constructor, at line XYZ" says more than failing test "Dynarray constructors, at line ZYX"
