我有一些摩卡测试如下所示。当我运行它们时，它们起作用。然后我再次运行它们中的一个会失败。然后我运行它们，然后它们工作，然后下一次，其他一些（看似）随机测试将失败。如果我的结构很差或编码错误，我很乐意听到。
有谁能告诉我为什么这些测试会随机失败？这让我想起了mongo的稳定性。
另一件事是：测试永远不会说出错了，只是它超时并且我应该确保调用done（）。 / data / mongoAccess代码位于测试块之下。

好的，我明白了。不幸的是，在我意识到我已经解决了改变的问题之前，我改变了我的问题的文本。在修复我的promise语法之后，我再也无法重现这个问题了。
我做的是这样的事情：
<EntityType Name="Attachment">
<Key>
<PropertyRef Name="Id"/>
</Key>
<Property Name="Id" Unicode="false" Type="Edm.String" Nullable="false"/>
<Property Name="Name" Unicode="false" Type="Edm.String"/>
<Property Name="ContentType" Unicode="false" Type="Edm.String"/>
<Property Name="Size" Type="Edm.Int32" Nullable="false"/>
<Property Name="IsInline" Type="Edm.Boolean" Nullable="false"/>
<Property Name="DateTimeLastModified" Type="Edm.DateTimeOffset"/>
</EntityType>
<EntityType Name="FileAttachment" BaseType="Microsoft.Graph.Attachment">
<Property Name="ContentId" Unicode="false" Type="Edm.String"/>
<Property Name="ContentLocation" Unicode="false" Type="Edm.String"/>
<Property Name="IsContactPhoto" Type="Edm.Boolean" Nullable="false"/>
<Property Name="ContentBytes" Type="Edm.Binary"/>
</EntityType>
<EntityType Name="ItemAttachment" BaseType="Microsoft.Graph.Attachment">
<NavigationProperty Name="Item" Type="Microsoft.Graph.OutlookItem" Nullable="false" ContainsTarget="true"/>
</EntityType>
当我把它切换到这个时：
mongo.removeApiCall("uri11").then(
mongo.removeApiCall("uri12").then(
mongo.insertApiCall("uri11", "type1", 2, "domain", "target", "url", "phrase", "d1|d1", data).then(

mongo.insertApiCall("uri12", "type2", 2, "domain", "target", "url", "phrase", "d1|d2").then(
mongo.removeApiCall("uri12", "type1", null, null, null, null, null, false).then(
mongo.findApiCall("uri12").then(function(result) {
assert.isArray(result);
assert.equal(1, result.length, "Array length is " + result.length);
assert.equal("type2", result[0].apiType);
mongo.findApiCall("uri11").then(function(result2) {
assert.isArray(result2);
assert.equal(1, result2.length);
mongo.removeApiCall("uri11").then(
mongo.removeApiCall("uri12").then(function() {
done();
}));
});
})))))));
