这似乎在SpecFlow V2中处理得更好：http://www.specflow.org/documentation/Parallel-Execution/

答案 2 :(得分：0)
我知道这是一篇旧帖子，但它引用了，所以这是我的解决方案：
只需用这样的自定义实现替换ScenarioContext：
public class ScenarioContextSafe
{
private static ScenarioContextSafe _current;
private static readonly object Locker = new object();
public static ScenarioContextSafe Current
{
get
{
lock (Locker) {
return _current ?? (_current = new ScenarioContextSafe());
}
}
}
public static void Reset()
{
lock (Locker) {
_current = null;
}
}
private readonly ConcurrentDictionary<string, object> _concurrentDictionary = new ConcurrentDictionary<string, object>();
public void Add(string key, object value)
{
_concurrentDictionary.TryAdd(key, value);
}
public void Set(object value, string key)
{
if (!_concurrentDictionary.ContainsKey(key))
_concurrentDictionary.TryAdd(key, value);
else
_concurrentDictionary[key] = value;
}
public void Remove(string key)
{
object result;
_concurrentDictionary.TryRemove(key, out result);
}
public T Get<T>(string key)
{
object result;
_concurrentDictionary.TryGetValue(key, out result);
return (T)result;
}
public bool ContainsKey(string key)
{
return _concurrentDictionary.ContainsKey(key);
}
public void Pending()
{
ScenarioContext.Current.Pending();
}
public ScenarioInfo ScenarioInfo{
get { return ScenarioContext.Current.ScenarioInfo; }
}
}
然后，在每个场景之前创建一个用于重置上下文的钩子
[BeforeScenario()]
public static void BeforeAllScenario()
{
ScenarioContextSafe.Reset();
}
我希望这有助于某人。
