# Use your network drive

> Mount your CIFS/SMB file share onto the runner so your flow can read and write files during a test run.

<Warning>
  This helper requires runner support. In QA Wolf-managed runs, the runner configures this automatically. If you're building a custom runner, see the [Client Reference](/qawolf/libraries/testkit/api-reference/client).
</Warning>

## Examples

**Mount your file share**

```typescript theme={null}
import { mountCifsShare } from "@qawolf/testkit";

const mountPoint = await mountCifsShare({
  share: "//server/share",
  mountPoint: "/mnt/share",
  username: process.env["SHARE_USERNAME"]!,
  password: process.env["SHARE_PASSWORD"]!,
});
```

**Read a file from your file share**

```typescript theme={null}
import { mountCifsShare } from "@qawolf/testkit";
import { readFileSync } from "fs";

const mountPoint = await mountCifsShare({
  share: "//server/share",
  mountPoint: "/mnt/share",
  username: process.env["SHARE_USERNAME"]!,
  password: process.env["SHARE_PASSWORD"]!,
});

const data = readFileSync(`${mountPoint}/test-data.csv`, "utf-8");
```

## When to use

* Your app reads or writes files that live on your network drive.
* Your flow needs test fixtures or input data from your network drive that can't be committed to a repository.
* Your app writes output files to your network drive and your flow needs to verify them.
* Your flow needs to upload files to your app that are sourced from your network drive.

## Full example

```typescript theme={null}
import { flow } from "@qawolf/flows/web";
import { mountCifsShare } from "@qawolf/testkit";

export default flow(
  "Upload file from your file share",
  { target: "Web - Chrome", launch: true },
  async ({ page, test }) => {
    await test("mount file share", async () => {
      const mountPoint = await mountCifsShare({
        share: "//server/share",
        mountPoint: "/mnt/share",
        username: process.env["SHARE_USERNAME"]!,
        password: process.env["SHARE_PASSWORD"]!,
      });

      await page.goto(process.env["BASE_URL"]!);
      await page.setInputFiles('[type="file"]', `${mountPoint}/upload.csv`);
    });

    await test("verify upload", async () => {
      await expect(page.getByText("Upload complete")).toBeVisible();
    });
  },
);
```
