sockets - Test harness software for networking failures -

-

During integration testing it is important to ensure that to ensure the different types of low-level networking failure It is necessary that these components are handled properly.

  • Connection refused
  • Never send any data with Remote and SEN / ACK Remote and Answers
  • Remote and only sends reset packets
  • The connection is established, but does not accept remote and packet, which causes endless re-launch

further .

This would be useful for simulating such failures for integration testing with web services, database calls etc.

Is this device a specific device (i.e. socket-level failures)? For example, there is a possibility that it will be a useless server that exhibits different types of failures on different ports.

Edit: After some additional research, it seems that it is possible to handle such a thing by using a firewall. For example, iptables has some options Which allows you to match packets (either randomly based on some configurable probability or on the basis of each NNT-packet) and then release them. So I am thinking that we can establish our "dirty server" with the firewall rules configured on a port-by-port basis so that we can check our apps. I would be interested to hear ideas about this approach.

Take a look at this.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
