# Testing Nfield surveys

_Test Surveys · SurveyTester Academy_

Nfield is a dedicated survey system in SurveyTester. A project set to **Nfield** (or to **Automatic**) recognises an
Nfield Online survey the moment the browser extension opens it: every page with its single-choice questions, grids and
number fields, and the error messages Nfield shows under a question. From there everything else in SurveyTester works
as usual - Auto Answer, Auto Complete, SurveyBots, test cases, issues and the Pages & Routing overview.

## What an Nfield survey looks like to a tester

Nfield Online interviews run on Nfield's own servers; the survey link points to an address containing `nfieldmr`,
and when you paste such a link into a new project, SurveyTester preselects Nfield for you. Every page shows one or more
questions with **Next** and, depending on the survey, **Back** and **Clear** buttons. When an answer is missing or not valid,
Nfield keeps the respondent on the page and shows a message below the question.

## Why this is hard to test without SurveyTester

- **No question names on screen.** Respondents never see the questionnaire's question names. SurveyTester reads them
  from the page, so every page and question in the result carries the name from the questionnaire.
- **Grids are built from cards.** Nfield draws a grid as a stack of rows, each with its own answer buttons.
  SurveyTester records each row with its scale.
- **Errors only show up after Next.** A message under a question is easy to overlook in a long run. SurveyTester stores
  it with the question, so every refused answer is visible in the result.

## Supported question types

| Nfield question type | How SurveyTester records it |
|---|---|
| Single choice | One option is chosen. |
| Single-choice grid | Every row is answered with one scale point. |
| Number field | A number is entered. |
| Text-only pages | Recorded as information pages with nothing to answer. |

Other question types are recorded as part of their page, but SurveyTester may not answer them automatically yet.
Answer them by hand, and SurveyTester continues with the next page.

## Errors and end page

- **Error messages.** The messages Nfield shows below a question are stored as errors of that question.
- **Navigation.** SurveyTester moves on with the survey's **Next** button and knows its **Back** button.
- **End page.** Complete, screenout and quota pages are recognised by the survey end page identifiers on the project;
  set them up before you rely on the outcome of automated runs. See
  [Survey end pages](https://www.surveytester.com/academy/en/company-admin-settings/survey-end-pages).

## Step by step

1. **Create the project.** Choose **Nfield** as the survey system, or leave it at **Automatic** - the survey is
   recognised either way. Paste the survey link.
2. **Start a test run** from the project with the SurveyTester browser extension, or let SurveyBots run the survey.
   The SurveyTester bar appears above it, and the first page is recorded as step 1.
3. **Answer the survey** by hand, or press **Auto Answer** and **Auto Next** to let SurveyTester fill the page and move
   on. Each page creates the next step.
4. **Check the result** on the Pages & Routing page: every page appears with its questions, every question with its
   answer options, grid rows and scale points.

## Good to know

- **Page and question names.** A page is named after the first question on it; questions keep their Nfield names.
- **Support is basic.** Nfield support covers the question types listed above. If your survey uses other question
  types or a page that SurveyTester does not read correctly, please send it to us - we extend the support from real
  pages.
