Looking for a cheap quick UI testing and monitoring Tool - end test and Ghost Inspector Review

Problem:  My client is looking for a simple tool to monitor a website is up and running and can run a small set of UI tests and asserts to verify it is working as expected.

Initial Hypothesis:  There are a lot of monitoring sites like uptime that meet this requirement, but I reviewed Ghost Inspector and endtest.  I am not looking to do full CI as I would look at Selenium WebDriver for an enterprise solution for UI testing.

Resolution:  Trial endtest and Ghost inspector on my O365 subscription to validate it monitors and alerts, can perform advanced logins and it can validate custom pages after JavaScript injection.  Price and feature wise both tools are pretty similar.

Ghost Inspector Initial Thoughts
Easy to use and there is a recording function for Chrome.  This review has put me off Ghost Inspector to some degree but definitely an excellent product to evaluate.
Bad review for Ghost Inspector but it does assume enterprise level UI testing more suited to tooling like Selenium.

endtest Initial Thoughts
Easy to use, setup testing in a matter of minutes, recorded actions and assertions.  The trial is limited as I could not check the scheduling mechanism, but end test looks like the ideal tool for my requirement.  Would need to go for the pro licence at $79 per month.  A simpler smaller option would be more attractive but let's see what the client thinks.

Other Tools for UI Testing:
Selenium
Selenium IDE is an excellent tool for UI testing and UI automation testing.  Here is a post on Selenium I did a few years back.

qTest Explorer
This is a Manual recording and documentation tool that records browser and desktop interaction.  It's straightforward to use and great for Manual UI testing.  It is not for automation or re-running test but great if the project requires manual testing and proof.

Basic Branching Strategy for TFS and GIT



  • The main difference between standard TFS branching strategy is that you branch more often for shorter time periods and check in small code change units into the "Development" branch.
  • Delete the black line once the feature is complete and checked back into the Development branch.  Can easily start a new functional local GIT branch to amend the next feature.
Note: Easy to also grab a GIT local branch from the Main branch (inline with you production code base), make changes and then when checked back in they hotfix goes into both the Main and Development code branches.

Interviewing Developers, Leads and Consultants for SharePoint projects

Overview:  Depending on the project will dictate the skills and experience I look for.  This post lists the skills I generally look for when hiring dev and leads for SharePoint based projects.  Firstly, I compile a list of skills for the project and ensure each developer role covers multiple areas/expertise types.  My general list is shown below.

Skill needed:

  • SharePoint
  • CSOM/REST
  • PHA
  • TFS / GIT
  • .NET/C# 
  • WCF / Web API
  • SQL Server 
  • Entity Framework/Code First
  • HTML/CSS
  • JQuery, 
  • Angular JS, KnockOut React VueJS, Other JScript Libraries
  • O365
  • Azure
  • Federation/Security
  • Agile/Scrum

I keep a scorecard and Notes that I fill in for each candidate.  If they score too low in the technical section, I don't start the Personal section, and until I think they are a good candidate then I start the problem solving which I find to be the best indicator of if a guy is going to work out.  Looking back at a lot of developers and leads hired, the 2 critical sections are problem-solving and admits limitations (the guys that don't know when to say "I don't know" are generally a problem if hired).

Example qus when trying to identify a candidates strengths:
QU: Difference/compare Web Services vs WCF vs Web API
ANS:
Web Services is the oldest, .asmx extension are ASP.NET Microsoft's web services.  HTTP protocol only and uses SOAP (XML).  Microsoft proprietary.
WCF was the next release and ends with the extension .svc.  Supports the following protocols: HTTP, HTTPS, TCP, Named Pipes, MSMQ.  WCF uses SOAP (XML)Complex to configure but offers flexibility.  Add REST support using webHttpBindings and then can use XML, JSON and ATOM data format.  IIS needs config change to support PUT and .. verbs.
WebAPI is part of MVC template wasn't originally.  Simple to setup and supports REST.  Lightweight and easy to setup.  Easy to consume.  HTTP protocol only. Supports XML and JSOM data format.


CSS Basic Qus (as I am rubbish, thanks to Jeff H):
QU: How can we add/implemented CSS to our pages (3 approaches)
ANS: Inline css, in the head section of the page or call/reference an external CSS file
QU: Explain Z-Index
ANS: Stack order
QU: Browser engines used
ANS:  IE uses Trident or now called HTMLEdge, Chrome & Opera use Blink; Safari uses webKit; Firefox/Mozilla uses Gecko.
QU: Explain block object positioning between: Absolute, relative and fixed. 
QU: Diff class selector vs and id selector
QU: Explain Display: None vs Display: Hidden

CSOM TLS Issue - The underlying connection was closed

Problem:  I have a console using CSOM that stopped working when the TLS settings were updated firm-wide.  The communication is between the console and a SharePoint farm, using CSOM, and now it no longer works.  The event log generates the following error message on the client machine: A fatal error occurred while creating an SSL client credential. The internal error state is 10013.

Initial Hypothesis: The outbound HTTPS traffic is the issue as the error is telling me that the mistake was creating the SSL client credential.  The console runs on a web server, and the TLS restriction change has caused the issue.  This issue is that the console running can't create an SSL client credential.  The TLS change was made to the console VM and not the SharePoint farm.  Here is the PS script to validate TLS versions written by Vadims Podans.


The post below helped me query the windows web servers to check the TLS settings using PowerShell.  I believe the outbound is controlled by the inbound TLS settings.

Resolution:  Change the console to use a know TLS version e.g., TLS1.2 as shown below:
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Alternatively, revert the TLS setting in the registry. Apparently, this means your server is more susceptible to attack.

Alternatively, specify all the portocols you support from the calling client side application ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls | SecurityProtocolType.Ssl3;

Read this section if you are still having issues.
Factors that Influence Settings:
My CSOM console sits on a VM that hosts IIS, so there are three components to ensure connectivity excluding networking:
1.> SharePoint Server needs to support the TLS version
2.> VM hosting my console's outbound SSL is also set by IIS local TLS settings, so if I want to speak on TLS to the SharePoint server, I also need to have SSL enabled (or registry hacked) on TLS1.2 on the IIS VM hosting my console.
3.> My Console needs to support TLS 1.2 or all versions so it can negotiate for itself.  Regedit to check TLS setting is shown below:
