[英]How to construct unit test
I have custom event logger, and I want to test it. 我有自定义事件记录器,我想对其进行测试。
[Test]
public void AddLogWithExceptionAndEventLogEntryTypeTest()
{
const string loggerName = "mockLoggerName";
var logger = new MyLogger(loggerName);
System.Diagnostics.EventLog log = new System.Diagnostics.EventLog("System");
string logValue = Guid.NewGuid().ToString();
logger.AddEntry(new Exception(logValue),EventLogEntryType.Error );
foreach (
EventLogEntry entry in log.Entries)
{
if (entry.Message.ToUpper().Contains(logValue))
{
//what can is do ?
}
}
}
What assert to use to give information, that entry was added ? 用来添加信息的断言是什么?
Is your intent to look through the log for text you just added? 您是否打算在日志中查找刚添加的文本? Then how about:
然后如何:
bool foundOne = false;
foreach (EventLogEntry entry in log.Entries)
{
if (entry.Message.ToUpper().Contains(logValue))
{
foundOne = true;
}
}
Assert(foundOne);
Personally, I would instead probably mock the logger, and instead assert that the methods of the mocked logger were called as expected. 就个人而言,我可能会模拟记录器,而是断言模拟记录器的方法已按预期方式调用。
