Database Errors codes returning from api layer to a ui layer sep project

I keep coming back to this but what should I be returning from my database service call in my WeightLifting Service I have this code.
public async void CopySessionsPlayersToWeightLiftingBySessionId(int sessionID)
{
List<SessionPlayer> sessionsPlayers = new
List<SessionPlayer>();
sessionsPlayers = db.SessionPlayer.Where(w => w.SessionId ==
sessionID).ToList();
if (sessionsPlayers != null)
{
List<WeightLifting> weightLiftings = new List<WeightLifting>();
foreach (var sessionPlayer in sessionsPlayers)
{
var player = db.Players.Where(w => w.Id ==
sessionPlayer.PlayerId).FirstOrDefault();
WeightLifting weightLifting = new WeightLifting();
weightLifting.SessionStartDate = sessionPlayer.StartDate;
weightLifting.SessionEndDate = sessionPlayer.EndDate;
weightLifting.TeamId=sessionPlayer.TeamId;
weightLifting.SessionId = sessionPlayer.SessionId;
weightLifting.PlayersId = sessionPlayer.PlayerId;
weightLifting.PU = player.DefaultPU;
weightLifting.PUReps = Convert.ToInt32(player.DefaultPUReps);
weightLifting.BP = player.DefaultBP;
weightLifting.TB = player.DefaultTB;
weightLifting.TBReps = Convert.ToInt32(player.DefaultTBReps);
weightLifting.OP = player.DefaultOP;
weightLifting.OPReps = Convert.ToInt32(player.DefaultOPReps);
weightLifting.APU = player.DefaultAdvancedPu;
weightLifting.APUReps = Convert.ToInt32(player.DefaultAdvancedPuReps);
weightLifting.IsActive = true;
weightLifting.IsDeleted = false;
weightLiftings.Add(weightLifting);
}
db.AddRange(weightLiftings);
db.SaveChanges();
}
}
As I am just doing a save out my http client call is basically this.
public async Task<HttpStatusCode>
CopySessionsPlayersToWeightLiftingBySessionId(int Id)
{
EnsureHttpClientCreated();
var json = JsonConvert.SerializeObject(Id);
var httpContent = new StringContent(json, Encoding.UTF8,
"application/json");
var httpResponse = await httpClient.PostAsync(Constants.BaseUrl
+ Constants.ApiSegmant +
Constants.CopySessionsPlayersToWeightLiftingBySessionId +
$"?Id={Id}", httpContent);
return httpResponse.StatusCode;
}
My Create Http Client code
private void EnsureHttpClientCreated()
{
if (httpClient == null)
{
CreateHttpClient();
}
}
private void CreateHttpClient()
{
_httpClientHandler = new HttpClientHandler
{
AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip
};
httpClient = new HttpClient(_httpClientHandler, false)
{
Timeout = _timeout
};
httpClient.DefaultRequestHeaders.UserAgent.ParseAdd(ClientUserAgent);
if (!string.IsNullOrWhiteSpace(Constants.BaseUrl))
{
httpClient.BaseAddress = new Uri(Constants.BaseUrl);
}
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(MediaTypeJson));
}
At the min only the ui will get a ok but how should I handle sending back an error here yes I could try catch around the save changes then put a BadContent but that feels messy?.

Consider using exception filters. They basically serve as a middleware that runs after your endpoint throws an exception to catch it and turn it into a specific response.

Properly Attach to existing chrome driver with C# Selenium Webdriver

I have used this method designed by Tarun Lalwani to attach a Selenium Chrome driver by reusing the url and the sessionID in C#. This attach is partly working but some driver methods such as FindElement(By.ID) display error "invalid argument: invalid locator (Session info: chrome=91.0.4472.114)" on this line:
var respBase = base.Execute(driverCommandToExecute, parameters);
My guess is that it is due to options or desired capabilities are empty when the driver is attached.But I havent find a way to properly set it on ReuseRemoteWebDriver.
I include an image of the look of the attached driver
here.
How can I solve this issue so I can attach the previous chrome driver and keep all expected selenium functionalities?
static void Main(string[] args)
{
InputSimulator teclado = new InputSimulator();
ChromeOptions options = new ChromeOptions();
options.UseSpecCompliantProtocol = true;
ChromeDriverService service = ChromeDriverService.CreateDefaultService(#"Thepathofchromedriver");
IWebDriver driver;
DesiredCapabilities capabilities = new DesiredCapabilities();
Uri myUri = new Uri("http://127.0.0.1:65431", UriKind.Absolute);
service.Port = 65431;
string ID = "1f42d5f0ad105910e8d2fc7be23480a9";
if (ID != "")
{
IWebDriver drivertest1 = new ChromeDriver(service, options);
IWebDriver drivertest = new ReuseRemoteWebDriver(myUri, ID,capabilities,options);
driver = drivertest;
}
else
{
IWebDriver drivertest = new ChromeDriver(service,options);
driver = drivertest;
}
IWebElement inputUser = driver.FindElement(By.Id("ID"));}
public class ReuseRemoteWebDriver : OpenQA.Selenium.Remote.RemoteWebDriver
{
private String _sessionId;
public ReuseRemoteWebDriver(Uri remoteAddress, String sessionId, OpenQA.Selenium.Remote.DesiredCapabilities capability, ChromeOptions options)
: base(remoteAddress,options)
{
this._sessionId = sessionId;
var sessionIdBase = this.GetType()
.BaseType
.GetField("sessionId",
System.Reflection.BindingFlags.Instance |
System.Reflection.BindingFlags.NonPublic);
sessionIdBase.SetValue(this, new OpenQA.Selenium.Remote.SessionId(sessionId));
}
protected override OpenQA.Selenium.Remote.Response
Execute(string driverCommandToExecute, System.Collections.Generic.Dictionary<string, object> parameters)
{
if (driverCommandToExecute == OpenQA.Selenium.Remote.DriverCommand.NewSession)
{
var resp = new OpenQA.Selenium.Remote.Response();
resp.Status = OpenQA.Selenium.WebDriverResult.Success;
resp.SessionId = this._sessionId;
resp.Value = new System.Collections.Generic.Dictionary<String, Object>();
return resp;
}
var respBase = base.Execute(driverCommandToExecute, parameters);
return respBase;
}
}
UPDATE: I could fix most issues, as I indicated in the reply.
the most important functionality I couldn't manage to recover was the inject js scripts with
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
var script = "your script";
js.ExecuteScript(script);
Any idea regarding how to recover the inject script functionality would be appreciated.

In case anyone is interested, I modified the previous class as following, so I can use the sendKeysToElement
public class ReuseRemoteWebDriver : OpenQA.Selenium.Remote.RemoteWebDriver
{
private String _sessionId;
public ReuseRemoteWebDriver(Uri remoteAddress, String sessionId, ChromeOptions options, ChromeDriverService service)
: base(remoteAddress, options)
{
//object x = driver;
this._sessionId = sessionId;
var sessionIdBase = this.GetType()
.BaseType
.GetField("sessionId",
System.Reflection.BindingFlags.Instance |
System.Reflection.BindingFlags.NonPublic);
//System.Collections.Generic.Dictionary<string, object> x = this.GetCapabilitiesDictionary(capability);
sessionIdBase.SetValue(this, new OpenQA.Selenium.Remote.SessionId(sessionId));
}
protected override OpenQA.Selenium.Remote.Response
Execute(string driverCommandToExecute, System.Collections.Generic.Dictionary<string, object> parameters)
{
if (driverCommandToExecute == OpenQA.Selenium.Remote.DriverCommand.NewSession)
{
var resp = new OpenQA.Selenium.Remote.Response();
resp.Status = OpenQA.Selenium.WebDriverResult.Success;
resp.SessionId = this._sessionId;
resp.Value = new System.Collections.Generic.Dictionary<String, Object>();
return resp;
}
if (driverCommandToExecute == "sendKeysToElement")
{
object[] array = (object[])parameters["value"];
string stringfinal = (string)array[0].ToString();
parameters.Add("text", stringfinal);
}
if (driverCommandToExecute == "executeScript")
{
Console.WriteLine("");
}
var respBase = base.Execute(driverCommandToExecute, parameters);
return respBase;
}
}
}
In other class I used the following method to properly used Selenium waits.
public Boolean WaitInteligente(WebDriverWait wait, string condition, By selector = null,
IWebElement optionalWebElement = null,string optionalstring = null,
bool optionalbool = false,bool devolverexcepcion=true )
{
TimeSpan Tiempo = wait.Timeout;
var globalclock = Stopwatch.StartNew();
Boolean stop = false;
double segundos = globalclock.Elapsed.TotalSeconds;
Exception exception = null;
//globalclock.Stop();
while (segundos <= Tiempo.TotalSeconds)
{
Thread.Sleep(500);
try
{
segundos = globalclock.Elapsed.TotalSeconds;
if (condition == "ElementExists")
wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementExists(selector));
if (condition == "ElementIsVisible")
wait.Until(ExpectedConditions.ElementIsVisible(selector));
if (condition == "ElementToBeClickable")
wait.Until(ExpectedConditions.ElementToBeClickable(selector));
if (condition == "ElementToBeSelected")
wait.Until(ExpectedConditions.ElementToBeSelected(selector));
if (condition == "FrameToBeAvailableAndSwitchToIt")
wait.Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(selector));
if (condition == "InvisibilityOfElementLocated")
wait.Until(ExpectedConditions.InvisibilityOfElementLocated(selector));
if (condition == "PresenceOfAllElementsLocatedBy")
wait.Until(ExpectedConditions.PresenceOfAllElementsLocatedBy(selector));
if (condition == "VisibilityOfAllElementsLocatedBy")
wait.Until(ExpectedConditions.VisibilityOfAllElementsLocatedBy(selector));
if (condition == "AlertIsPresent")
wait.Until(ExpectedConditions.AlertIsPresent());
if (condition == "ElementToBeSelected")
wait.Until(ExpectedConditions.ElementToBeSelected(optionalWebElement));
if (condition == "InvisibilityOfElementWithText")
wait.Until(ExpectedConditions.InvisibilityOfElementWithText(selector,optionalstring));
if (condition == "StalenessOf")
wait.Until(ExpectedConditions.StalenessOf(optionalWebElement));
if (condition == "TextToBePresentInElement")
wait.Until(ExpectedConditions.TextToBePresentInElement(optionalWebElement,optionalstring));
if (condition == "TextToBePresentInElementLocated")
wait.Until(ExpectedConditions.TextToBePresentInElementLocated(selector, optionalstring));
if (condition == "TextToBePresentInElementValue")
wait.Until(ExpectedConditions.TextToBePresentInElementValue(selector, optionalstring));
if (condition == "TitleContains")
wait.Until(ExpectedConditions.TitleContains(optionalstring));
if (condition == "TitleIs")
wait.Until(ExpectedConditions.TitleIs(optionalstring));
if (condition == "UrlContains")
wait.Until(ExpectedConditions.UrlContains(optionalstring));
if (condition == "UrlMatches")
wait.Until(ExpectedConditions.UrlMatches(optionalstring));
if (condition == "UrlToBe")
wait.Until(ExpectedConditions.UrlToBe(optionalstring));
if (condition == "FrameToBeAvailableAndSwitchToIt")
wait.Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(optionalstring));
if (condition == "AlertState")
wait.Until(ExpectedConditions.AlertState(optionalbool));
if (condition == "ElementSelectionStateToBe")
wait.Until(ExpectedConditions.ElementSelectionStateToBe(selector,optionalbool));
if (condition == "ElementSelectionStateToBe")
wait.Until(ExpectedConditions.ElementSelectionStateToBe(selector, optionalbool));
stop = true;
break;
}
catch (Exception e)
{
e = new Exception(selector.ToString() + condition + e.Message);
exception = e;
}
}
if (!stop && devolverexcepcion)
throw exception;
return stop;
}
The methods that are not working properly when attached are
driver.FindElement(By.Id) and driver.FindElement(By.ClassName) which can be easily circumvented by using a By.CssSelector call to the ID or Classname respectively.
The most important functionality I couldn't recover was the inject js scripts with
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
var script = "your script";
js.ExecuteScript(script);
Any idea regarding how to recover the inject script functionality would be appreciated.

Saucelabs Selenium not using proxy details for RemoteWebDriver (C#)

I'm using the Saucelabs Selenium implementation to automate my testing across multiple devices and platforms.
Using the demo code from SauceLabs (below) doesn't work behind a proxy.
I've tried adding the proxy details to the DesiredCapibilities but this doesn't seem to do anything
[TestMethod]
public void TestSauceLabs()
{
DesiredCapabilities caps = new DesiredCapabilities();
caps.SetCapability("browserName", "Safari");
caps.SetCapability("platform", "macOS 10.13");
caps.SetCapability("version", "11.1");
caps.SetCapability("username", _sauceUserName);
caps.SetCapability("accessKey", _sauceAccessKey);
caps.SetCapability("name", _name);
var tags = new List<string> {"demoTest", "sauceDemo"};
caps.SetCapability("tags", tags);
caps.SetCapability("maxDuration", 3600);
caps.SetCapability("commandTimeout", 600);
caps.SetCapability("idleTimeout", 1000);
caps.SetCapability("build", "SauceDemo");
/****************************************
* Edited demo code here
* Added proxy config to DesiredCapabilities **
*/
var proxy = new Proxy
{
IsAutoDetect = false,
HttpProxy = $"{_proxyScheme}://{_proxyHost}:{_proxyPort}",
SslProxy = $"{_proxyScheme}://{_proxyHost}:{_proxyPort}",
FtpProxy = $"{_proxyScheme}://{_proxyHost}:{_proxyPort}"
};
caps.SetCapability(CapabilityType.Proxy, proxy);
/*
*****************************************/
var uri = new Uri("https://ondemand.eu-central-1.saucelabs.com/wd/hub");
_driver = new RemoteWebDriver(uri,
caps, TimeSpan.FromSeconds(600));
_javascriptExecutor = ((IJavaScriptExecutor) _driver);
_javascriptExecutor.ExecuteScript("sauce:context=Open SauceDemo.com");
_driver.Navigate().GoToUrl(_url);
_javascriptExecutor.ExecuteScript("sauce:context=Sleep for 10000ms");
Thread.Sleep(10000);
Assert.IsTrue(true);
var passed = true;
_javascriptExecutor.ExecuteScript("sauce:job-result=" + (passed ? "passed" : "failed"));
_driver?.Quit();
}

Found the solution was to use the HttpCommandExecutor when using the RemoteWebDriver behind a proxy.
Here is my example code:
[TestMethod]
public void TestSauceLabs_Chrome()
{
var remoteOptions = new Dictionary<string, object>
{
{ "username", _sauceUserName },
{ "accessKey", _sauceAccessKey },
{ "name", _name },
{ "maxDuration", 3600 },
{ "commandTimeout", 600 },
{ "idleTimeout", 1000 }
};
var options = new ChromeOptions()
{
PlatformName = "Windows 10",
BrowserVersion = "latest"
};
//Remote options need to be global
options.AddAdditionalCapability("sauce:options", remoteOptions, true);
var caps = options.ToCapabilities();
/*
Using the HttpCommandExecutor persists the proxy details
and allows you to pass in credentials if required
*/
var executor = new HttpCommandExecutor(
new Uri("https://ondemand.eu-central-1.saucelabs.com/wd/hub"),
TimeSpan.FromSeconds(600))
{
Proxy = GenerateProxy()
};
_driver = new RemoteWebDriver(executor, caps);
_javascriptExecutor = ((IJavaScriptExecutor)_driver);
_javascriptExecutor.ExecuteScript($"sauce:context=Open {_url}");
_driver.Navigate().GoToUrl(_url);
_javascriptExecutor.ExecuteScript("sauce:context=Sleep for 10000ms");
Thread.Sleep(10000);
Assert.IsTrue(true);
var passed = true;
_javascriptExecutor.ExecuteScript("sauce:job-result=" + (passed ? "passed" : "failed"));
_driver?.Quit();
}
public WebProxy GenerateProxy()
{
var proxy = new WebProxy
{
Address = new Uri($"{_proxyScheme}://{_proxyHost}:{_proxyPort}"),
BypassProxyOnLocal = false,
UseDefaultCredentials = _networkCredential != null,
Credentials = _networkCredential
};
return proxy;
}

How can I turn ON radio of a Wifi adapter that is actually OFF?

I'm using Managed Wifi to get the radio state of my Wifi adapter.
How can I turn the radio ON in case it is actually off ?
Something like this :
WlanClient wlanClient = new WlanClient()
var targetInterface = wlanClient.Interfaces.FirstOrDefault()
if (targetInterface != null)
{
bool radioIsOff = targetInterface .RadioState.PhyRadioState[0].dot11SoftwareRadioState == Wlan.Dot11RadioState.Off;
if (radioIsOff)
{
// TODO
}
}

I just added this to the WlanInterface class of the Managed Wifi API :
IntPtr radioStatePtr = new IntPtr(0L);
try
{
Wlan.WlanPhyRadioState radioState = new Wlan.WlanPhyRadioState();
radioState.dwPhyIndex = 0; // TODO : can change ???
radioState.dot11HardwareRadioState = Wlan.Dot11RadioState.On; // ignored in fact, according to http://msdn.microsoft.com/en-us/library/windows/desktop/ms706791(v=vs.85).aspx
radioState.dot11SoftwareRadioState = Wlan.Dot11RadioState.On;
radioStatePtr = Marshal.AllocHGlobal(Marshal.SizeOf(radioState));
Marshal.StructureToPtr(radioState, radioStatePtr, false);
Wlan.ThrowIfError(
Wlan.WlanSetInterface(
client.clientHandle,
info.interfaceGuid,
Wlan.WlanIntfOpcode.RadioState,
(uint)Marshal.SizeOf(typeof(Wlan.WlanPhyRadioState)),
radioStatePtr,
IntPtr.Zero));
}
finally
{
if (radioStatePtr.ToInt64() != 0)
Marshal.FreeHGlobal(radioStatePtr);
}
Tested on Win 7.

I was struggling with this and I just want to share my solution
(download managed wifi recommended above)
Add WlanApi.cs and Interop.cs to your project.
Add using NativeWifi.
In WlanApi.cs
change to:
public IntPtr clientHandle;
(You need the clientHandle. Not sure why it was set to private?)
Use this code:
string arg1 = "true"; //set to false if you want to turn it off.
arg1 = arg1.ToLower();
IntPtr radioStatePtr = new IntPtr(0L);
try
{
WlanClient wc = new WlanClient();
foreach (var iface in wc.Interfaces)
{
//WlanInterface
if(iface.InterfaceName.ToLower()=="wifi")
{
Wlan.WlanPhyRadioState radioState = new Wlan.WlanPhyRadioState();
radioState.dwPhyIndex = 0;
if(arg1=="true")
{
radioState.dot11HardwareRadioState = Wlan.Dot11RadioState.On;
radioState.dot11SoftwareRadioState = Wlan.Dot11RadioState.On;
}
else
{
radioState.dot11HardwareRadioState = Wlan.Dot11RadioState.Off;
radioState.dot11SoftwareRadioState = Wlan.Dot11RadioState.Off;
}
radioStatePtr = Marshal.AllocHGlobal(Marshal.SizeOf(radioState));
Marshal.StructureToPtr(radioState, radioStatePtr, false);
Wlan.WlanSetInterface(wc.clientHandle, iface.InterfaceGuid, Wlan.WlanIntfOpcode.RadioState, (uint)Marshal.SizeOf(typeof(Wlan.WlanPhyRadioState)), radioStatePtr, IntPtr.Zero);
}
}
}
finally
{
if (radioStatePtr.ToInt64() != 0)
Marshal.FreeHGlobal(radioStatePtr);
}
Good luck :)
