 1The test failed due to a connection issue with the PostgreSQL database. The specific error message is:
 2
 3Connection to localhost:5433 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
 4
 5This indicates several potential problems:
 6
 71. **Database Not Running**: The PostgreSQL server might not be running on your local machine. Ensure that the PostgreSQL service is up and accepting connections.
 8
 92. **Incorrect Port**: The test is attempting to connect to PostgreSQL on port `5433`. Verify that PostgreSQL is configured to listen on this port. The default port for PostgreSQL is `5432`. You might want to check your PostgreSQL configuration file (`postgresql.conf`) to see if the port is set to `5433` and whether the server is correctly configured to listen on that port.
10
113. **Firewall/Network Issues**: If the PostgreSQL server is running, there might be firewall rules or network policies preventing access to the specified port. Make sure that your firewall settings allow connections on port `5433`.
12
134. **TCP/IP Settings**: Check the PostgreSQL configuration to see if it is set to allow TCP/IP connections. This is typically managed in the `postgresql.conf` file through the `listen_addresses` setting, and you may also need to check the `pg_hba.conf` file to ensure that the appropriate host and user permissions are set up for connections.
14
155. **Network Interface Configuration**: If you're running PostgreSQL in a containerized environment or a virtual machine, ensure that the network interface configurations allow for connections to `localhost` or the specific IP address you are trying to connect to.
16
176. **Connection String or Configuration Error**: Make sure that your application's connection string or configuration is set up correctly to point to the correct database instance, user, and password, in addition to the hostname and port.
18
197. **Postmaster Not Accepting Connections**: Finally, the error suggests checking if the "postmaster" (PostgreSQL server process) is accepting connections. This can be done by trying to connect to the database using a tool like `psql` or a database client, specifying the same hostname and port.
20
21In summary, start by ensuring that the PostgreSQL server is running properly and is configured to accept connections on the correct port, then check your application settings to confirm that everything is set up correctly.

1AssertionError: Timed out retrying after 5000ms: Expected to find element: `[role="dot-duration-8UNFGPZIGCHD"]`, but never found it.

 1The error message you're encountering indicates that a test in a Cypress-based test suite has failed due to a timeout when trying to find an element with the specified selector `[role="dot-duration-8UNFGPZIGCHD"]`. Here are some possible reasons why this test may have failed and some suggestions for troubleshooting:
 2
 31. **Element Not Present**:
 4- The most likely reason is that the element with the role `dot-duration-8UNFGPZIGCHD` does not exist in the DOM at the time the test is executed. This could be due to changes in the application’s state that prevent the element from rendering.
 5
 62. **Timing Issue**:
 7- The element may not be present yet because it takes longer than expected to load. This could be due to slow network conditions, slow server response, or heavy client-side processing. Consider increasing the timeout or using `cy.wait()` to pause the test before checking for the element.
 8
 93. **State of the Application**:
10- Ensure that the application is in the correct state to display the element you’re testing. If this element is dependent on prior actions or specific states, verify they have been completed successfully.
11
124. **Selector Issues**:
13- The selector `[role="dot-duration-8UNFGPZIGCHD"]` might be incorrect. Double-check the role attribute in the rendered application. If the role or any part of the selector is dynamic (changing on each render), your test may need to be updated accordingly.
14
155. **Visibility of Element**:
16- The element might be present but not visible. Make sure that it is not hidden by CSS or conditional rendering.
17
186. **Test Environment**:
19- Verify if the test is running in the correct environment and that all dependencies (like services the application relies on) are functioning.
20
217. **Error in the Application Code**:
22- There might be a bug in the application that is preventing the element from rendering. Check the application logs or run the application manually to ensure there are no runtime errors.
23
24### Suggestions for Resolution
25
26- **Debugging**: Use `cy.debug()` or `cy.log()` to output useful information just before the assertion to understand the current state of the application and what’s in the DOM.
27
28- **Increase Timeout**: If timing is an issue, consider increasing the default timeout for finding the element:
29javascript
30cy.get('[role="dot-duration-8UNFGPZIGCHD"]', { timeout: 10000 }).should('exist');
31
32
33- **Add Waiting Mechanisms**: If there are asynchronous operations that load the element, consider using appropriate commands or waiting strategies:
34javascript
35cy.wait(2000); // For demonstration, not a best practice. Prefer to wait for specific conditions.
36
37
38By investigating these areas, you should be able to identify why the test failed and take the necessary steps to correct it.

 1The error message you provided indicates that a test case in a Spock specification failed because the actual value did not match the expected value. Let's break down the message:
 2
 3- **Condition not satisfied**: This indicates that an assertion in your test has failed.
 4- **actual == 3**: This is the assertion that is failing. The test expected the actual value to be `3`.
 5- **| |**: This part of the message shows the comparison. The left side is your actual value, and the right side is the expected value.
 6- **1 false**: Here, `1` is the value that was evaluated in the test (this is what `actual` is), and `false` indicates that this does not satisfy the condition that it should be equal to `3`.
 7- **at projektor.example.spock.FailingSpec.should fail with output(FailingSpec.groovy:22)**: This part shows where the failure occurred, specifically in `FailingSpec.groovy` at line 22.

 9### Possible Reasons for Failure:
10
111. **Wrong Value Calculation**: The actual value `1` might be coming from some calculations or method calls that are not returning what you expect. You might want to check the logic that produces this value.
122. **Test Setup Issues**: Ensure that any setup or stubbed data used in the test is correct. Misconfiguration in the setup, such as incorrect mock responses, could lead to unexpected actual values.
133. **State Issues**: If the test relies on shared state or if some dependencies are not reset properly between test runs, this could lead to unexpected values.
144. **Logic Errors**: If the code being tested contains bugs, this could cause it to return incorrect results.
15
16### Steps to Diagnose the Issue:
17
181. **Review the Test**: Look closely at the test case to understand how the actual value `1` is being generated.
192. **Debugging**: Use debugging tools to step through the code that generates the actual output. This may help identify why the output is not as expected.
203. **Print Statements**: Add logging or print statements in the code to identify the flow of data to understand where things are going wrong.
214. **Check Expected Value**: Ensure that `3` is indeed the expected value, and evaluate if the conditions that lead to it should be updated.

23By investigating these areas, you should be able to identify the cause of the test failure and address it accordingly.
