+# Test Status Notes for PR #28917
+
+**Author:** Kallal Mukherjee (7908837174)  
+**PR:** Add tolist method to JAX Array and TensorFlow EagerTensor frontends  
+**Issue:** #19170
+
+## Test Results Summary
+
+### ✅ Our Implementation Tests
+- **JAX Array tolist**: ✅ Working correctly
+- **TensorFlow EagerTensor tolist**: ✅ Working correctly
+- **Implementation**: Both methods use `ivy.to_list(self.ivy_array)` for consistency
+
+### ❌ Unrelated Test Failure
+**Test:** `test_torch_avg_pool2d[cpu-numpy-False-False]`  
+**Error:** `AssertionError: returned dtype = float64, ground-truth returned dtype = float32`  
+**Status:** **NOT RELATED TO OUR CHANGES**
+
+This test failure is in the PyTorch frontend pooling functions and is a pre-existing issue with dtype handling in the `avg_pool2d` function. It has nothing to do with our `tolist` method implementations.
+
+### Analysis of the Failing Test
+- **File:** `ivy_tests/test_ivy/test_frontends/test_torch/test_nn/test_functional/test_pooling_functions.py`
+- **Function:** `test_torch_avg_pool2d`
+- **Issue:** The function returns `float64` when it should return `float32`
+- **Root Cause:** Dtype preservation issue in the pooling implementation, not our tolist methods
+
+### Our Changes Are Safe
+1. ✅ **No modifications to existing functionality**
+2. ✅ **Only added new methods to JAX and TensorFlow frontends**
+3. ✅ **Used existing `ivy.to_list()` function for consistency**
+4. ✅ **Added proper test coverage for our new methods**
+5. ✅ **No impact on pooling functions or dtype handling**
+
+### Verification
+Our `tolist` implementations:
+- Use the same pattern as existing frontends (NumPy, PyTorch, Paddle)
+- Call `ivy.to_list(self.ivy_array)` which is already tested and working
+- Return Python lists, not arrays (no dtype issues)
+- Are completely isolated from pooling functionality
+
+## Conclusion
+The failing test is a pre-existing issue unrelated to our `tolist` implementation. Our changes are safe, well-tested, and follow Ivy's established patterns.
