I am trying to follow the recommendation to upgrade the DHF using gradle but I am running through an issue that I cannot het my head around.

The build succeeds but the redeployment fails Any idea on how to fix this ?

note that the login info is provided properly in the gradle.properties

I'm going through a process of upgrading my Selenium Hub/Nodes to version 3.3. Everything works fine, but I want to make sure I have optimal configuration... problem is I can't find a complete list of Hub/Node properties anywhere.

I've looked through:

• https://seleniumhq.github.io/docs/grid.html
• http://www.seleniumhq.org/docs/07_selenium_grid.jsp
• https://github.com/SeleniumHQ/selenium/wiki/Grid2
• https://github.com/SeleniumHQ/selenium/blob/master/java/server/src/org/openqa/grid/common/defaults/DefaultNodeWebDriver.json
• https://github.com/SeleniumHQ/selenium/blob/master/java/server/src/org/openqa/grid/common/defaults/DefaultHub.json

These docs only list some of the properties through example configs, but none of them seem like a complete list and more importantly none of them actually state what these properties do. Where is the documentation for a complete list of configuration properties for Selenium Hub/Nodes?

I am getting this error when i reload the dynamic page.

I have a legacy webform project in which is necessary to integrate signalr Technology I understood that the signalr/hubs is generated dinamically, however in my specific project i couldn make it work.

I tried to load all urls paths such as:

<%----%>

To turn around this i generate the signalR in another project which is working fine and i copied to my scripts folder /Scripts/SignalR/Hub.js and i referenced it in client side.

It worked fine because my client could establish connection with my chatHub(serverside) initializing my chat variable as below:

However after that i got i error in the negociate process between server to client as the image below:

I think is because when the server trys to comunicate with the client it generates the url as [signalr/hub], but as i mentioned before, I'm using the /Scripts/SignalR/Hub.js file to instance de connection to the hub.

How can i fix this negociate issue between server to the client?

Here is my structure files

I faced a problem with my jest+enzyme mount() testing. I am testing a function, which switches displaying components.

Switch between components: when state.infoDisplayContent = 'mission' a missionControl component is mounted, when state.infoDisplayContent = 'profile' - other component steps in:

I wrote this web application that after inputing coordinates of a city (latitude, longitude) (source: json) returns the list of 10 closest earthquakes that happened in the US. Now, I have 2 problems:

Problem 1.

1. I enter coordinates of a chosen city (e.g. Seattle) and I get the proper results.
2. I enter coordinates of the second city (e.g. Washington D.C.), I get different (proper) results.
3. I enter the same coordinates od the first city (e.g. Seattle) and the results are the same as with the previous second search.
4. I enter the coordinates of third, fourth, sixth etc. city and I keep getting the same results.

It's like the application was being stuck (after 2-3 proper queries?). Sometimes I get three different results in a row, sometimes four, sometimes just two and later same results are being printed. If I hardcode the coordinates into Servlet into the Java method, the results are different each time, so I'm guessing there is some problem passing the input fields into the Java method. It doesn't matter if I chose from the list the city or I type in coordinates myself.

Problem 2.

1. I choose a city from the dropdown list.
2. Coordinates are being input into the input html form, e.g. Kansas City: Latitude: 39.099728 Longitude -94.578568.
3. I add letters/signs to the latitude e.g. 39.099728sdjfhjsdf, longitude: -94.578568 and I press submit.
4. I get info that the field is not formatted properly (that's OK until now).
5. I chose from a dropdown list another city, the input fields are being filled with new coordinates and I press submit, but I keep getting the warning the number is not formatted properly (like the program even though the input is new would be still reading 39.099728sdjfhjsdf).

Here is the minimal working example. Project wrote in Eclipse.

I am getting this error from clicking a button to view a profile of user because it is a public get route, but it seems the issue is that the person provided a wrong GitHub username linked to his account, but I have tried creating an if statement, to check if what a user provides is wrong or correct, but it seems not to work at all.

Below is the error and the other files.
