Also, HTTP headers are case-insensitive, so, you can declare them with standard Python style (also known as "snake_case").

So, you can use `user_agent` as you normally would in Python code, instead of needing to capitalize the first letters as `User_Agent` or something similar.

        TestDataStoreParams testParams = new TestDataStoreParams(paramMap);

        assertEquals("value1", testParams.get("key1"));
    }

    // Test case conversion through ParamMap (camelCase to snake_case)
    public void test_caseConversion() {
        dataStoreParams.put("camelCaseKey", "value1");
        // ParamMap should handle case conversion
        assertNotNull(dataStoreParams.get("camelCaseKey"));
