Introduction

The Soroban test framework is a crucial tool for developers to ensure the stability and reliability of their applications. However, like any other complex system, it is not immune to issues and bugs. In this article, we will delve into a specific problem that has been reported by users, namely a flaky RPC test in the Soroban test framework. We will explore the issue, its symptoms, and possible solutions to resolve it.

What is a Flaky Test?

A flaky test is a test that fails intermittently, without any apparent reason. It is a test that passes in some runs, but fails in others, even when the code has not changed. Flaky tests can be frustrating for developers, as they can make it difficult to identify and fix issues in the code.

The Issue

The issue we are dealing with is a flaky RPC test in the Soroban test framework. The test is supposed to pass, but it fails intermittently with a "fee limit exceeded" error. The error message indicates that the test is failing because of a resource limit exceeded error.

Symptoms

The symptoms of this issue are as follows:

The test fails intermittently with a "fee limit exceeded" error.
The error message indicates that the test is failing because of a resource limit exceeded error.
The test passes in some runs, but fails in others, even when the code has not changed.

Possible Causes

There are several possible causes of this issue:

Resource Limit Exceeded: The test is exceeding the resource limit, which is causing the error.
RPC Test Flakiness: The RPC test is flaky, which is causing the test to fail intermittently.
Code Changes: The code has changed, which is causing the test to fail.

Troubleshooting Steps

To troubleshoot this issue, we can follow these steps:

Check the Code: Check the code to see if there are any changes that could be causing the test to fail.
Check the Resource Limit: Check the resource limit to see if it is being exceeded.
Run the Test Multiple Times: Run the test multiple times to see if it is flaky.
Check the RPC Test: Check the RPC test to see if it is flaky.

Solutions

To resolve this issue, we can try the following solutions:

Increase the Resource Limit: Increase the resource limit to see if it resolves the issue.
Fix the RPC Test: Fix the RPC test to make it more robust and less prone to flakiness.
Change the Code: Change the code to see if it resolves the issue.

Conclusion

In conclusion, the flaky RPC test issue in the Soroban test framework is a complex problem that requires careful troubleshooting and analysis. By following the troubleshooting steps and trying the solutions, we can resolve this issue and ensure that the test passes consistently.

Recommendations

Based on our analysis, we recommend the following:

Increase the Resource Limit: Increase the resource limit to see if it resolves the issue.
Fix the RPC Test: Fix the RPC test to make it more robust and less prone to flakiness.
Change the Code: Change the code to see if it resolves the issue.

Future Work

In the future, we plan to:

Improve the RPC Test: Improve the RPC test to make it more robust and less prone to flakiness.
Increase the Resource Limit: Increase the resource limit to ensure that the test passes consistently.
Change the Code: Change the code to see if it resolves the issue.
