+# Writing mock apis
+
+1. First step is to create a new file typescript file in the [src/test-routes](../src/test-routes) folder:
+1. All the needed imports are from the `api` folder
+1. Define the category for your apis using `app.category("vanilla" | "azure" | "optional", () => {})`
+1. Start writing mock apis inside the `category` callback
+
+## Example
+
+```ts
+import { app, json } from "../../api";
+
+app.category("vanilla", () => {
+  app.get("/test", "GetMyTest", (req) => {
+    return {
+      status: 200,
+      body: json({
+        foo: "succeeded",
+        bar: "wut",
+      }),
+    };
+  });
+
+  app.post("/test", "PostMyTest", (req) => {
+    req.bodyEquals({ foo: "123", bar: "456" });
+    return {
+      status: 200,
+      body: json({
+        succeeded: true,
+      }),
+    };
+  });
+});
+```
+
+## How to build response
+
+Return the reponse object. [See type](../src/api/mock-response.ts)
+
+```ts
+// Minimum requirement is the status code.
+return {
+  status: 200,
+};
+```
+
+### Return a body
+
+```ts
+// Return json
+return {
+  status: 200,
+  body: json({ foo: 123 }),
+};
+
+// Return raw content
+return {
+  status: 200,
+  body: {
+    contentType: "application/text",
+    rawContent: "foobar",
+  },
+};
+```
+
+### Return headers
+
+```ts
+// Return json
+return {
+  status: 200,
+  headers: {
+      MyHeader: "value-1"
+      MyHeaderOther: req.headers.MyRequestHeader
+  }
+};
+
+```
+
+## How to validate the request:
+
+### Validate the body
+
+- With `req.bodyEquals`
+
+This will do a deep equals of the body to make sure it match.
+
+```ts
+app.post("/example", "Example", (req) => {
+  req.bodyEquals({ foo: "123", bar: "456" });
+});
+```
+
+- With `req.rawBodyEquals`
+
+This will compare the raw body sent.
+
+```ts
+app.post("/example", "Example", (req) => {
+  req.rawBodyEquals('"foo"');
+});
+```
+
+### Custom validation
+
+You can do any kind of validation accessing the `req: MockRequest` object and deciding to return a different response in some cases.
+You can also always `throw` a `ValidationError`
+
+Example:
+
+```ts
+app.post("/example", "Example", (req) => {
+  if (req.headers.MyCustomHeader.startsWith("x-foo")) {
+    throw new ValidationError("MyCustomHeader shouldn't start with x-foo", null, req.headers.MyCustomHeader);
+  }
+});
+```
