http-server-sim
HTTP Server Simulator is a .NET tool that runs a Web API simulating HTTP endpoints, supporting the development and testing of components that use HTTP.
http-server-sim can be called from the shell/command line.
Usage
Installation
Install the latest version from NuGet:
dotnet tool install --global http-server-sim
Once http-server-sim is installed as a global tool, it can be executed from any folder. For other versions and more information, visit NuGet and dotnet tool install.
Rule file
The simulation of endpoints is based on a rule file. Here’s how it can be set up:
- Create a rule file defining the endpoints and their behaviors.
- Place the rule file in the appropriate directory.
- Run the simulator with the rule file.
Example of rule file.
{
"rules": [
{
"name": "customers-post",
"description": "",
"conditions": [
{ "field": "Method", "operator": "Equals", "value": "POST" },
{ "field": "Path", "operator": "Contains", "value": "/customers" }
],
"response": {
"statusCode": 200
}
}
]
}
Example command (assuming that the file rule.json is in the current folder where the command http-server-sim is being executed):
http-server-sim --Rules rules.json
The following POST request is handled using rule customers-post
:
curl --location 'http://localhost:5000/customers' --header 'Content-Type: application/json' --data '{"id":10,"name":"Juan"}' -v
http-server-sim
returns a response with 200.
The following GET request:
curl --location 'http://localhost:5000/customers' -v
returns 404 with content Rule matching request not found
http-server-sim output:
Request:
HTTP/1.1 - GET - http://localhost:5000/customers
Headers:
Accept: */*
Host: localhost:5000
User-Agent: curl/8.7.1
Body:
[Not present]
End of Request
warn: HttpServerSim.App[0]
Rule matching request not found.
Response:
Status Code: 404
Headers:
[Not present]
Body:
Rule matching request not found
End of Response

Rule conditions
When http-server-sim
processes a request, it uses rule conditions to match a rule to the request.
Example of conditions:
"conditions": [
{ "field": "Method", "operator": "Equals", "value": "POST" },
{ "field": "Path", "operator": "Contains", "value": "/customers" }
]
A rule with these conditions is applied when:
- The request method is POST, and
- The URL path contains /customers.
There are two types of conditions, Method
and Path
- Method Conditions: These specify the HTTP method (e.g.,
GET
,POST
) that the request must match. - URL Path Conditions: These specify the URL path that the request must match.
The supported operators are: Equals
, StartWith
, and Contains
Response messages
When http-server-sim
identifies a rule that matches a request, it prepares a response message based on the response
section of the rule.
Response properties:
Property | Description |
---|---|
statusCode | Status code of the response message. Default: 200 |
headers | A collection of headers. Example: "headers": [ { "key": "Server", "value": ["http-server-sim"] } ] |
contentType | Content type of a response with a content, this value is used to create the header Content-Type . Example: application/json |
contentValue | Value used in the content, can be a text, a full path to a file, or a file name when the file exists in the current directory. Example: person-1.json |
contentValueType | Defines whether contentValue is a text or a file. Possible values: Text or File . Default: Text |
encoding | Defines an encoding to apply to the content. Default: None . Supported values: GZip |
Example of a response defining a message with status code 400.
"response": {
"statusCode": 400
}
Example of a response defining a message with status code 200 and headers Server
(with a single value) and header-1
(with multiple values)
"response": {
"statusCode": 200,
"headers": [
{ "key": "Server", "value": ["http-server-sim"] },
{ "key": "header-1", "value": ["val-1", "val-2"] }
]
}
Example of a response with a plain text content.
"response": {
"contentType": "text/plain",
"contentValue": "Thank you for the notification",
}
Example of a response using a json file that exists in the current directory.
"response": {
"contentType": "application/json",
"contentValue": "person-1.json",
"contentValueType": "File"
}
Example of a response using an in-line json.
"response": {
"contentType": "application/json",
"contentValue": "{\"name\":\"Juan\"}"
}
Example of a response using a json file that exists in the current directory and compressing the content with gzip.
"response": {
"contentType": "application/json",
"contentValue": "person-1.json",
"contentValueType": "File",
"encoding": "GZip"
}
