gdl | Graph Definition Language

kandi X-RAY | gdl Summary
Inspired by the popular graph query language Cypher, which is implemented in Neo4j, I started developing an ANTLR grammar to define property graphs. I added the concept of subgraphs into the language to support multiple, possible overlapping property graphs in one database. For me, this project is a way to learn more about ANTLR and context-free grammars. Furthermore, GDL is used for unit testing and graph definition in Gradoop, a framework for distributed graph analytics. The project contains the grammar and a listener implementation which transforms GDL scripts into property graph model elements (i.e. graphs, vertices and edges). There is also a Rust version of GDL available on GitHub.

I'm mocking negative responses with PayPal API in order to get the responses and handle correctly a critical part of payment when the client has approved the payment via onApprove method.
I'm using GuzzleHttp + Laravel to capture the approval from the client. I get the COMPLETED status within the complete object. So the request is working properly.
ANSWER

Can't make this pass the login test with Laravel scaffolding.
I tried accessing database $user with $user = User::first(); and also using factory User::factory()->create();. In both cases I'm able to successfully dd($user) info, so it means $user exists and can be accessed.
I also tried hardcoding credentials with bcrpyt() and Hash::make password - where the error also appears to happen.
I'm not ussing RefreshDatabase trait.
ANSWER
Answered 2021-Jan-24 at 00:13Your test_log_user() function is using the already hashed password for your user as the form password which, is then being hashed again before being checked against the value in the database.
The user factory sets the password field for a user to be a hash of the word password (unless you have changed this). For example:

Answered 2020-Nov-07 at 12:51idl and idlde (GUI) behave differently: while idl requires the functions to be stored in the separate .pro files, idlde handles the functions in the same file as the run script, as long as they are declared before any other commands.
gdl behaves just like idl, so functions' declarations in the separate files resolved the issue.
