Currently comparing sbe tag/value pairs in unit tests is hard, because we must use value::compareValue function that returns a tag/value pair and than we have to assert that tag is NumberInt32 and value is the expected comparison value.

There are different parts of code that handle it differently:
Example 1
Example 2
Example 3
 
The goal of this ticket is two implement a simple way to compare two SBE values.
 
For example: ASSERT_SBE_VALUE_EQ/GT/LT(expectedTag, expectedValue, actualTag, actualValue)
 
The requirements are:
1. Use value::compareValue under the hood to ensure correct semantics.
2. Prints expected and actual values on assertion failure for easy debugging
3. Can support collation if needed.
