Summary:
This change will keep project consistency.
This change repeat the previous commit 582738bdc8.
That was created by sammy-SC and reviewed by shergin
That changed
* `ASSERT_TRUE` -> `EXPECT_TRUE`
* `ASSERT_NEAR` -> `EXPECT_NEAR`
* `ASSERT_EQ` -> `EXPECT_EQ`
That said
> 1. Replace ASSERT_* with EXPECT_*. Assert is a fatal assertion. Expect is non-fatal assertion. So if assert fails, tests do not continue and therefore provide less information.
>
> 2. Rename tests in `RawPropsTest.cpp` from `ShadowNodeTest` to `RawPropsTest`.
>
