Unfortunately, the problem is exactly that we're not (fully) understanding the content of `ASSERT_TRUE` and related macros (`ASSERT_FALSE`, `ASSERT_THAT(..., IsTrue(opt.has_value()))`, etc.), which then affect code outside and following the macros. So, ignoring them would not solve anything. Until we can understand the googletest macros, there is little value in check any tests that use them. That is what this patch accomplishes.
