Can someone please refer me some examples or some provide guidance on how can we test table rendered using react-table with react testing library? I have use cases like sort, search, filter, and row expansion and server side pagination.

I am required to functional test a web app built using angular 5. The app has a lot of chart widgets - basically reporting done through the chart based on the values in the sql server database for specific criteria given through the query bar. I basically have to check for dynamic changes in the charts based on updates - add/delete/change in the database. There are several different charts which get affected by those changes and I have to validate both the ui and db using automation. I have been reading that protractor can be used for e2e testing, would I be able to validate data updates and changes to the chart using protractor or please suggest me a tool for this. Also I am not seeing a lot of blogs for checking dynamically generated charts using protractor. Please help me with any material you can.
Could be really difficult to do using protractor if we are talking about a production-like environment, with dynamic data. Develop such an e2e test like the case that you are describing will, at the best case, provide you a flaky test that will provide you a large quantity of fake-failings.
If you are using a library to generate the charts like Highcharts, i would divide the testing on two pieces:
A) The easier part: Check that the endpoints that need to provide the data to the charts are retrieving properly the data comparing it to the present data on the DB. You could use a module like protractor-intercept ( https://www.npmjs.com/package/protractor-intercept ) to easily handle that. With these, you will be testing that the data arrives properly from the DB to Client.
B) Difficult part: Mock the data retrieved for those endpoints on a test environment ( yes, you will need help from development team). If you know the data that you are expecting, will be easier to assure that is being properly rendered on the front-end charts.
Those kind of tests are hard to deal. A months ago, I had to design one of those and finally the team decided to cover only the api responses, instead of all the e2e flow.
I have setup my application for REST access as per documentation. The default routes are working well. I am able to retrieve, update and delete records, however, I am not sure how I could filter data sending parameters to the controller. I wonder if I can do that using querystring or if there is a better way to accomplish that. Please can someone give me directions?
Reads about the Request object in the manual. And use the Search Plugin for filtering.
The search plugin comes with a lot of documentation that explains how to use it as well.
Your question is so generic that a proper answer would end up in a whole article - which I'm obviously not going to write, there is enough information available on HTTP requests and query params. Use Google or read these links:

I created a dataset using 2 extractors: a "many rows" extractor which is then called by a "just one row" extractor via the "URLs from another API / Chain APIs" option. This has given me the data that I need and I have saved it as a dataset. Although the dataset is working I'm lost as to how to use the REST API to retrieve it?
I'm aware that there used to be an "integrate" button on the dataset page which would outline how to use an external client library to get the data but in it's absence now I don't know which of the APIs to use and how to use them?
I've attempted at using the "Query Methods" GET call "/store/connector/{id}/_query" but it requires an "id" which I don't know where to find from? I attempted to use the "_connectorVersionGuid" value when I saved the dataset as JSON but that didn't work.
Any help and advice would be much appreciated.
Thanks,

AJ,
Francesco here, from import.io.
First of all, thanks for formulating the question so clearly.
I have bad news and good news.
The bad news is at the moment Bulk and Chain are only available as client side feature, so it's not really possible to call a chain with a single REST call.
The good news is that we are actually working on it :)
Bulk as an API is actually in beta testing, and I hope to have a Chain as an API as well.
A workaround I sometimes use myself is to use an external integration as a service platform, like Node-RED (http://nodered.org/) or built.io (https://www.built.io/)
Call me crazy, but I'm looking for a service that will deliver autocomplete functionality similar to Google, Twitter, etc. After searching around for 20 min I thought to ask the geniuses here. Ideas?
I don't mind paying, but it would great if free.. Also is there a top notch NLP service that I can submit strings to and get back states, cities, currencies, company names, establishments, etc. Basically I need to take unstructured data (generic search string) and pull out key information with relevant meta-data.
Big challenge, I know.
Sharing solutions I found after further research.

If you dont want to implement it yourself, you can use this service called 'Autocomplete as a Service' which is specifically written for these purposes. You can access it here - www.aaas.io.
you can add metadata with each record and it returns metadata along with the matching results. Do check out demo put up on the home page. It has got a very simple API specifically written for autocomplete search
It does support large datasets and you can apply filters as well while searching.
Its usage is simple - Add your data and use the API URL as autocomplete data source.
Disclaimer: I am founder of it. I will be happy to provide this service to you.
I am working on a web application for a client that uses a postgresql database. I want the client to be able to go to a certain area of the site where the data from the database is displayed in graph form (for example, sales figures over a 6 month period). Is there a plugin I could use for this (I don't have any experience of this, so an easy one, or one with tutorials available would be great). I had a look at BIRT, which says it has a web based option but I couldn't really figure it out. I don't want the client to have to download and go through another program, I just want them to go to a url within their site, and it's all just presented to them there and then.
Any sort of pointers in the right direction would be greatly appreciated.
Thank you.
HighCharts, at http://www.highcharts.com/, works well for this case -- I use it fairly often. It supports Ajax data feeds in JSON format, so you can write an endpoint which returns the JSON representing the data from Postgres and which gets called from a JavaScript function which creates the graphs using that data (you would place that call in a ready function).
Also, if you're using Postgres 9.3 or higher, it supports JSON natively, so you can do the JSON conversion in the SQL query itself, as opposed to post-processing the results in your Python or other backend code.
Highcharts is reasonably flexible and allows for a variety of nice-looking, functional charts and graphs. If you want to get much fanicer, d3 may be worth a look. These are some the types of graphs/charts it can do: https://github.com/mbostock/d3/wiki/Gallery
I have not used d3 myself, however.
For the scenario you described above, Highcharts seems like it would work just fine.
It's been a while, and a lot has happened since 2016. There is now ChartJS as well - http://chartjs.org/, for example, which is easier to use than HighCharts and very flexible (I've used both).
What they both don't do is dynamic data. If you want that your client decides which data he wants to watch - that part you need to write yourself.
