I've got a basic web-component-tester project which works fine when I'm online.
If I switch to flight mode, it seems to fail to connect to Selenium, and instead gives a largely useless error message after about 60s delay: "Error: Unable to connect to selenium".
Edit 2: I've narrowed the problem down in the following question, but I'd still like to know how to avoid it with web-component-tester:
Why does NodeJS request() fail on localhost in flight mode, but not 127.0.0.1? (Windows 10)
Edit: After some digging, it's something to do with DNS resolver somewhere beneath selenium-standalone failing while in flight mode, and not a lot to do with web-component-tester.
After inserting some debug logging into selenium-standalone, I tracked down the failure point to the check for whether Selenium is running. When online, this works fine, but when offline I get:
// check-started.js, logging the error inside the request() call:
Error: getaddrinfo ENOENT localhost:60435
at Object.exports._errnoException (util.js:1022:11)
at errnoException (dns.js:33:15)
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:76:26)
The following seem to describe similar situations, but I don't see how to persuade selenium-standalone nor web-component-tester to specify an IP address family to even try the suggested solutions:
https://github.com/nodejs/node/issues/4825
https://github.com/nodejs/node/issues/10290
node.js http.request and ipv6 vs ipv4

How to solve this error?
Looks like you are using the main branch of caliper-benchmarks. I would suggest you https://github.com/hyperledger/caliper-benchmarks/blob/main/networks/fabric/README.md
From what you have posted, you should use the latest available version of caliper which is 0.4.2, not 0.4.0. To do so the command you should issue is
npm install --only=prod #hyperledger/caliper-cli
You should bind to the latest 2.2 sdk (don't bind to 2.1 as fabric doesn't support 2.1). Note this is selecting the version of the sdk used to interact with a fabric network, not the version of the fabric network you are using. 2.2 will work with a fabric 2.2 and later 2.x versions
npx caliper bind --caliper-bind-sut fabric:2.2
Finally it looks like you tried to change the version number in the network configuration file. Don't change the version (it must be 2.0.0) as it refers to the version of the network configuration file and not the version of fabric you want to test
As you look to be using test-network, depending on which branch of fabric-samples you are using defines the version of fabric. The main branch tests the latest version of fabric which should have no problems.

I have (and am constrained to use) janusgraph to create a persona repository. I will be using a graphDB, largely because persona relationships are as important as persona attributes and the structure needs to be fluid. I need to create a Node.js application (+ pug & stylus eventually) to do CRUD operations on the data in the graphDB but I don't understand how to connect the client to the server. (Research has shown solutions for this problem but only with different components in place - Neo4j, OrientDB, etc)
I can start gremlin-server successfully and then I have tried creating a gremlin-console connection such as the following
/opt/janusgraph-0.2.2-hadoop2/bin/gremlin.sh /opt/janusgraph-0.2.2-hadoop2/conf/gremlin-server/gremlin-server.yaml
where the yaml looks like this:
(As well as localhost, I also tried the host's specific IP address, and both options with and without the square brackets, but with similar results)

Clearly, I've assumed or configured something(s) incorrectly, even in the console to server yaml and I don't know if the same yaml file would work for a Node.js client to connect.
I think I want the console connection so I can import the starter data from a graphml file and thereafter create new entries, query them, update them & delete them from the front end Node.js application.
What do I need to do to ?
The following doesn't create any connections from Gremlin Console to Gremlin Server:
/opt/janusgraph-0.2.2-hadoop2/bin/gremlin.sh /opt/janusgraph-0.2.2-hadoop2/conf/gremlin-server/gremlin-server.yaml
gremlin.sh does not take a Gremlin Server yaml file as an argument. Simply start bin/gremlin.sh and then write connect commands:
gremlin> :remote connect tinkerpop.server conf/remote.yaml
where remote.yaml points at Gremlin Server. You can read more about this in detail in a variety of places but I'll just point you to the TinkerPop reference documentation here.

You are mixing a lot of different versions so it's hard to say what will work. First of all, TinkerPop recommends that you try to match the versions of the server with the version of the client. So that means that if you you use 3.3.1 on the server then you should try to use 3.3.1 of a client (in your case gremlin-python). Next, you are using orientdb-gremlin with 3.0.2 which appears to be bound to TinkerPop 3.3.0,
https://github.com/orientechnologies/orientdb-gremlin/blob/3.0.2/driver/pom.xml
which means that for best results you should probably use 3.3.0 on Gremlin Server and gremlin-python. Now, while I mention all this about "matching versions" I will say that it is possible to mix versions, but matching will help limit the things that can go wrong as you're just getting started so I'd encourage you to start there.
As for your error, I think you installed the wrong dependencies. You should have done:
bin/gremlin-server.sh -i com.orientechnologies orientdb-gremlin-server 3.0.2
as orientdb-gremlin-server will bring in OrientEmbeddedFactory as well as the orientdb-gremlin dependencies. I also think that your orientdb-empty.properties file is missing some configuration options - see what is defaulted and what is not here.
We are running mocha nodejs tests with protractor on Sauce Labs and the attribute 'build' is being ignored. This is my protractor.conf.js
multiCapabilities: [
{
name: 'chrome-tests-windows',
browserName: 'chrome',
version: '52',
platform: 'Windows 7',
shardTestFiles: true,
maxInstances: 25,
build: 'solisko-1',
tags: ['tag1', 'tag2']
}]
When I look at the metadata in Sauce Labs Dashboard I see this:
Build null
Tags ["tag1","tag2"]
Browser googlechrome
Browser version 52.0.2743.82
OS Windows 2008
Any idea why the build name is ignored?
I guess, for the build to be populated on Sauce platform. You need to send the below property in Protractor config file. Check here
/** * Use sauceBuild if you want to group test capabilities by a
build ID */
sauceBuild?: string;
I dont see a build option in capabilities object as per the documentation here
From different source I found out that this is the correct attribute:
multiCapabilities: [
{
Build: 'some-build-name',
BuildName: 'some-build-name',
name: 'chrome-tests-mac',
browserName: 'chrome',
version: '52',
platform: 'OS X 10.12',
shardTestFiles: true,
maxInstances: 25
}
]
