Testing

You can quite easily test this library without executing real requests. To do that just mock any of the endpoints using their interface (e.g. IInstitutionsEndpoint). Alternatively you can also use the INordigenClient directly.

Example

using System.Net;
using Moq;
using RobinTTY.NordigenApiClient.Contracts;
using RobinTTY.NordigenApiClient.Models.Errors;
using RobinTTY.NordigenApiClient.Models.Responses;

namespace RobinTTY.NordigenApiClient.Tests.Mocking;

public class AccountsEndpointTests
{
    [Test]
    public async Task Test()
    {
        // Arrange
        var institutionsEndpointMock = new Mock<IInstitutionsEndpoint>();
        var institutionId = "some_id";
        institutionsEndpointMock.Setup(expression: s => s.GetInstitution(
            It.IsAny<string>(),
            It.IsAny<CancellationToken>())).ReturnsAsync(() =>
            new NordigenApiResponse<Institution, BasicError>(HttpStatusCode.OK, true,
                new Institution(institutionId, "NAME", "BIC", 90,
                    new List<string>(), new Uri("https://example.com")), null)
        );

        // Act
        var response = await institutionsEndpointMock.Object.GetInstitution(institutionId);

        // Assert
        Assert.Multiple(() =>
        {
            Assert.That(response.StatusCode, Is.EqualTo(HttpStatusCode.OK));
            Assert.That(response.Error, Is.Null);
            Assert.That(response.Result?.Id, Is.EqualTo(institutionId));
        });

       // Alternatively also using NordigenClient mock
        var nordigenClientMock = new Mock<INordigenClient>();
        nordigenClientMock.Setup(s => s.InstitutionsEndpoint).Returns(institutionsEndpointMock.Object);

        var response2 = await nordigenClientMock.Object.InstitutionsEndpoint.GetInstitution(institutionId);

        Assert.Multiple(() =>
        {
            Assert.That(response2.StatusCode, Is.EqualTo(HttpStatusCode.OK));
            Assert.That(response2.Error, Is.Null);
            Assert.That(response2.Result?.Id, Is.EqualTo(institutionId));
        });

    }
}
