test failing driver connect

[DrAli]

When I try to initiate and connect with a new driver and run "npm run test 01" 

I get test fails. 

I checkout the git checkout 01-connect-to-neo4j  and add my uri, user, password and run npm run test 01 and it passes.  

So I copied the entire file and went back to the main branch and with the neo4j.js file removed all the content and pasted in the code that worked .    Ran it  - and it FAILED...   stuck - help

@DrAli - Which course are you talking about specifically? Also - you mention failures, but you don't share what those failures are. Kind of hard to help...

[DrAli]

My apologies:  you are correct  -   I left out some details 

Course is:  

Building Neo4j Applications with Node.js

set up the neo4j.js   file

in terminal    -      npm run test 01

> neoflix-api-node@0.1.0 test
> node --experimental-vm-modules node_modules/jest/bin/jest.js 01

@DrAli ,

Modify the connection string for the driver to match your sandbox instance as explained here:

https://graphacademy.neo4j.com/courses/app-nodejs/1-driver/2-connection-strings/

Our sandboxes are currently in the process of migrating to Neo4j 5.4 but the connection for the driver should work as it did for Neo4j 4.x.

[DrAli]

I did follow those instructions. 

I just copied and pasted from the other branch - and got it to work that way.   There are differences in the code that may explain the first one failing  -  but those changes were not part of the assignment - specifically the export closeDriver function  lines 59 to 61

Can you share your neo4j.js file please?

[DrAli]

you can only upload jpegs here -  but you can access the file if you are in the course - by using the git checkout 01-connect-to-neo4j 

[adam_cowley]

You should be able to copy and paste your code into the reply window and wrap it in backticks to format it correctly.  I would like to understand what has happened in your case so I can make sure that others don't run into the same issue.
