Moq extensions for Dapper methods.
Mocking a call to Query
with a simple type:
[Test]
public void QueryGeneric()
{
var connection = new Mock<IDbConnection>();
var expected = new[] { 7, 77, 777 };
connection.SetupDapper(c => c.Query<int>(It.IsAny<string>(), null, null, true, null, null))
.Returns(expected);
var actual = connection.Object.Query<int>("", null, null, true, null, null).ToList();
Assert.That(actual.Count, Is.EqualTo(expected.Length));
Assert.That(actual, Is.EquivalentTo(expected));
}
Mocking a call to Query
with a complex type:
[Test]
public void QueryGenericComplexType()
{
var connection = new Mock<IDbConnection>();
var expected = new[]
{
new ComplexType { StringProperty = "String1", IntegerProperty = 7 },
new ComplexType { StringProperty = "String2", IntegerProperty = 77 },
new ComplexType { StringProperty = "String3", IntegerProperty = 777 }
};
connection.SetupDapper(c => c.Query<ComplexType>(It.IsAny<string>(), null, null, true, null, null))
.Returns(expected);
var actual = connection.Object.Query<ComplexType>("", null, null, true, null, null).ToList();
Assert.That(actual.Count, Is.EqualTo(expected.Length));
foreach (var complexObject in expected)
{
var match = actual.Where(co => co.StringProperty == complexObject.StringProperty && co.IntegerProperty == complexObject.IntegerProperty);
Assert.That(match.Count, Is.EqualTo(1));
}
}
Mocking a call to ExecuteScalar
:
[Test]
public void ExecuteScalar()
{
var connection = new Mock<IDbConnection>();
const int expected = 77;
connection.SetupDapper(c => c.ExecuteScalar<int>(It.IsAny<string>(), null, null, null, null))
.Returns(expected);
var actual = connection.Object.ExecuteScalar<int>("", null, null, null);
Assert.That(actual, Is.EqualTo(expected));
}
Mocking a call to QueryAsync
[Test]
public async Task QueryAsyncGeneric()
{
var connection = new Mock<DbConnection>();
var expected = new[] { 7, 77, 777 };
connection.SetupDapperAsync(c => c.QueryAsync<int>(It.IsAny<string>(), null, null, null, null))
.ReturnsAsync(expected);
var actual = (await connection.Object.QueryAsync<int>("", null, null, null, null)).ToList();
Assert.That(actual.Count, Is.EqualTo(expected.Length));
Assert.That(actual, Is.EquivalentTo(expected));
}
Mocking a call to ExecuteScalarAsync
:
[Test]
public void ExecuteScalarAsync()
{
var connection = new Mock<DbConnection>();
const string expected = "Hello";
connection.SetupDapperAsync(c => c.ExecuteScalarAsync<object>(It.IsAny<string>(), null, null, null, null))
.ReturnsAsync(expected);
var actual = connection.Object
.ExecuteScalarAsync<object>("")
.GetAwaiter()
.GetResult();
Assert.That(actual, Is.EqualTo(expected));
}
