HCV- adding code–part 4
Now it is time to write some code . However, the implementation should be in a different class than the health check itself – to can be tested.
The code is as follows:
using System;
using System.Collections.Generic;
using System.Reflection;
using System.Runtime.CompilerServices;
[assembly: InternalsVisibleTo("TestHealthCheckVersion")]
namespace HCVersion
{
internal class HCV
{
static Version versionEntry;
static Version versionHCV;
static HCV()
{
var ass = Assembly.GetEntryAssembly();
versionEntry = ass.GetName().Version;
versionHCV = Assembly.GetExecutingAssembly().GetName().Version;
}
public string GetStartingAssemblyInformation()
{
return versionEntry.ToString();
}
public string GetHCVAssemblyInformation()
{
return versionHCV.ToString();
}
}
}
The internals visible to is for running tests successfully.
The code for getting the real Health Check is
using Microsoft.Extensions.Diagnostics.HealthChecks;
using System;
using System.Collections.Generic;
using System.Dynamic;
using System.Threading;
using System.Threading.Tasks;
namespace HCVersion
{
public class HealthCheckVersion : IHealthCheck
{
public Task<HealthCheckResult> CheckHealthAsync(HealthCheckContext context, CancellationToken cancellationToken = default)
{
var hcv = new HCV();
var res = HealthCheckResult.Healthy(hcv.GetStartingAssemblyInformation(),
new Dictionary<string, object>()
{
{"Entry",hcv.GetStartingAssemblyInformation() },
{"HCV",hcv.GetHCVAssemblyInformation() }
});
return Task.FromResult( res);
}
}
}
