QUESTION
I'm trying to validate a JSON file in Visual Basic code. I've been looking for documentation on Newtonsoft however, they only offer sample code in C#. I basically want to use a schema string to validate some JSON files from a database in VB. How would the code below (written in C#) look like if it was written in VB?
How do you write
JsonSchema schema = JsonSchema.Parse(schemaJson);
In Visual Basic Code?

I have some ascii banners saved to plain text files that I use for different things and have used various ways to randomize the colors, but I haven't come up with a way to give every character a different color yet. I'm thinking there's probably a way to do an array to make it happen, but can't seem to quite get there - I'm aware of things like toilet and lolcat but I'm not able to use those currently (using centos). Here's what I've done so far:
change each file to a random color:
echo -e "\e[38;5;$(shuf -i 1-255 -n 1)m$(
you can do this with $RANDOM too:
echo -e "\e[38;5;$(( $RANDOM % 256 ))m$(
change each line in the file to a different color:

I would like to write a file into a Dockerfile. I don't want to import the file.
I would like the simplest solution, something like the solution that is not working. I would like to avoid to repeat many echo with each time the name of the file...
Thanks for help !
...ANSWER
Answered 2021-Feb-04 at 09:57In fact, the problem has nothing to do with Docker but with the way you're using the echo command.
If you use double-quote, the blank lines will be removed. To keep blank lines, you need to use simple quote (and remove the \ at the end of the lines).
You can try on your terminal :
QUESTION
I am trying to leverage Karate (https://github.com/intuit/karate) as a key component in an overall testing strategy for testing containerized, cloud-based microservices. Assuming that both the microservice under test and Karate have their own containers, the process is as follows:
- Fetch each container for local deployment
- Build (via gradle) the components in the Karate container (assume there are Java classes required by our mocks)
- Deploy (via gradle) the mocks and get them running in standalone mode
- Inject information about the mocks into the YAMLs of the microservice
- Build and deploy the microservice locally
- Run Karate tests (passing information about the mocks and/or environment) via CLI
My first question is whether or not this is a Good Idea(TM) or a Bad Idea(TM). On the surface it seems both reasonable and achievable but I am wondering if I am trying to use Karate in a way that it was never meant to be used. I toyed with the idea of keeping all the Karate stuff (including the mock sever) in the tests themselves, but then steps #3-5 would have to inject the mock information into the microservice, then run commands to get the microservice built and deployed all within test suite, which seemed to me like a Bad Idea(TM). Better instead to do this as part of a pipeline in a Jenkins job right?
My second question is how to best export mocks, files and Java dependencies for outside use (to support step numbers 2-3), for example here is the file structure:
...ANSWER
Answered 2020-Dec-08 at 02:21Answer to your second question is here: https://stackoverflow.com/a/58339662/143475
In my opinion, there is no Right Way™ to orchestrate your mocks and application-under-test. The approach you proposed will work, what I would do is use the --network option in Docker, for e.g. if the network is called mocks and you have to decide and perhaps expose a port number e.g. 8080, you set the URL-s in the second container as http://mocks:8080
You may get some ideas from this page on Karate's distributed-testing guide: https://github.com/intuit/karate/wiki/Distributed-Testing
Note that Karate mocks are designed to require only a JRE and the "fatjar". This can simplify things, for e.g. you may not even need to "Dockerize" things, just have java on the PATH and point to your *.feature files and you are done. Even if you use Java code, you can either add those to the CLASSPATH or you could build a "fatjar" yourself using maven-shade.
As you said, the option with the least moving parts may be to have the mocks stood-up in the same Java project. Advantages are:
- you can dynamically choose a port and pass it to the main app config
- starting and stopping and co-ordinating the 2 processes is easier (Java code)
- CLASSPATH is automatically taken care of
- if you get ambitious and attempt code-coverage in the future, can be easier

QUESTION
I have this Output component which should be rendered when it get props from the parent component.
How can I do this? Right now, it renders when I click a button but without the getTranslate function getting called. In debugger I can see that the component has the props needed, it just doesn't run my getTranslate function
...ANSWER
Answered 2020-Sep-24 at 13:34The probable problem is you are not calling getTranslate function, looks like it should be getTranslate(); also you need to update state once you receive data.. see I have placed comments to guide to towards a solution... getTranslate is not returning any value, and the place you are calling it not appropriate...

From inside the cloned folder I used:
...ANSWER
Answered 2020-Jun-23 at 05:04There may be one culprit gem here but you will run into this problem again and again unless you fix your underlying approach.
Look at your gems environment; all gems are installed into one folder, regardless of the project you’re working on. So, if you have two projects with conflicting dependencies you will get this problem again.
There are tools, like RVM, which let you create environments for each project. So, each project has its own separate collection of gems and even distinct versions of Ruby if you need 2.7 in one project and 2.5 for another.
See "Easy way to setting Ruby Version Manager (RVM) on projects" for how to use RVM and create a gemset for each project.
