编写测试案例(Test Cases)必须定义Test Fixture，在NUnitLite里使用属性[TestFixture]标识该类为Test Fixture。具体的测试就是该类的方法(Methods)。NUnitLite支持SetUp和TearDown，SetUp在执行测试案例之前先执行，用于初始化和分配资源，可以通过属性[SetUp]指定SetUp方法;TearDown在执行完测试案例后执行，用于释放相应的资源，可以使用属性[TearDown]指定TearDown方法。属性[Test]用于定义需要执行的测试案例，Test Runner会执行Test Fixture下所有的[Test]方法。
下面为测试案例的编写，也就是[Test]方法。
[Test]
public void ExecuteNonQueryTest()
{
int i = sqlCe.ExecuteNonQuery("delete from t");
Assert.That(i, Is.GreaterThan(-1));
i = sqlCe.ExecuteNonQuery("insert into t (f1, f2) values (1, 'abc')");
Assert.That(i, Is.GreaterThan(-1));
i = sqlCe.ExecuteNonQuery("update t set f2 = 'xyz' where f1 = 1");
Assert.That(i, Is.GreaterThan(-1));
}
[Test]
public void ExecuteReaderTest()
{
SqlCeDataReader reader = sqlCe.ExecuteReader("select * from t");
Assert.NotNull(reader);
Assert.True(!reader.IsClosed);
while (reader.Read())
{
Assert.That(Is.Equals(reader["f2"], "abc"));
}
reader.Close();
}
[Test]
public void ExecuteDataSetTest()
{
DataSet ds = sqlCe.ExecuteDataSet("select * from t");
foreach (DataRow dr in ds.Tables[0].Rows)
{
Assert.That(dr["f2"], Is.EqualTo("xyz"));
}
}
[Test]
[ExpectedException(typeof(ApplicationException))]
public void ThrowsException()
{
throw new ApplicationException("an application exception");
}
public void ExecuteNonQueryTest()
{
int i = sqlCe.ExecuteNonQuery("delete from t");
Assert.That(i, Is.GreaterThan(-1));
i = sqlCe.ExecuteNonQuery("insert into t (f1, f2) values (1, 'abc')");
Assert.That(i, Is.GreaterThan(-1));
i = sqlCe.ExecuteNonQuery("update t set f2 = 'xyz' where f1 = 1");
Assert.That(i, Is.GreaterThan(-1));
}
[Test]
public void ExecuteReaderTest()
{
SqlCeDataReader reader = sqlCe.ExecuteReader("select * from t");
Assert.NotNull(reader);
Assert.True(!reader.IsClosed);
while (reader.Read())
{
Assert.That(Is.Equals(reader["f2"], "abc"));
}
reader.Close();
}
[Test]
public void ExecuteDataSetTest()
{
DataSet ds = sqlCe.ExecuteDataSet("select * from t");
foreach (DataRow dr in ds.Tables[0].Rows)
{
Assert.That(dr["f2"], Is.EqualTo("xyz"));
}
}
[Test]
[ExpectedException(typeof(ApplicationException))]
public void ThrowsException()
{
throw new ApplicationException("an application exception");
}
在 NUnitLite中进行检验值还是使用Assert，但是不能使用NUnit下的AreEquels等判断方法,需要使用Assert.That和Is 类组合完成AreEquels等判断函数的功能。同时NUnitLite还是支持异常的捕捉(ExpectedException)。
程序运行后会生成运行结果如下：
