# Testing Survalyzer surveys

_Test Surveys · SurveyTester Academy_

Survalyzer is a fully supported survey system in SurveyTester. A project set to **Survalyzer** (or to **Automatic**)
recognises a Survalyzer survey the moment the browser extension opens it: every page with its questions, answer
options, matrix rows, open fields and "not answered" options, the text pages in between and the page at the end. From
there everything else in SurveyTester works as usual - Auto Answer, Auto Complete, SurveyBots, test cases, issues and
the Pages & Routing overview.

## What a Survalyzer survey looks like to a tester

Survalyzer surveys run as a web app: the survey link opens it once, and from then on every page is drawn in the same
browser window under the same address. The respondent answers, clicks **Next** (in German surveys **Weiter**) and the
next page appears without the page reloading. Most questions offer a "not answered" option, and some pages show the
**Next** button only after a fixed viewing time.

## Why this is hard to test without SurveyTester

- **One address for the whole survey.** Because the address never changes, neither the browser history nor the link
  tells you where you are. SurveyTester notices every page change in the window and records each page as a step of
  its own.
- **A loading screen before the first page.** The app shows a spinner while it starts. SurveyTester waits until the
  first question is there instead of recording an empty page.
- **Timed pages.** When the **Next** button appears only after a viewing time, Auto Next waits for it instead of
  getting stuck.
- **Limits that only show up as an error.** A number field often reveals its allowed range only in the error message
  ("less than or equal to 5"). SurveyTester reads the limit from the message and answers within it on the next try.
- **"Not answered" everywhere.** SurveyTester keeps these options apart from the real answers, so they can be chosen
  on purpose in a test case but are never mixed with other answers.

## Supported question types

| Survalyzer question type | How SurveyTester records it |
|---|---|
| Single choice | One option is chosen. |
| Multiple choice | Several options are ticked; a "not answered" option is ticked alone. |
| Option with a text or number field ("other, please specify") | The option and its field are recorded together; a number field gets a number in its range. |
| Matrix (one answer per row), with a "not answered" column | Every row is answered with one scale point. |
| Matrix with several answers per row, or with an open field in a cell | Every row gets its ticks; an open cell is filled with a fitting text or number. |
| Open text | A fitting text is entered. |
| Number field | A number within the allowed range is entered; a "not answered" option next to the field is recorded with it. |
| Text page | Recorded as an information page with nothing to answer. |

## Errors and end page

- **Error messages.** When Survalyzer refuses to move on, its messages are stored as errors of the page and of the
  question they belong to. The answers given so far are kept for the next attempt.
- **End page.** A page without questions and without a **Next** button - the thank-you page or the notice that the
  survey is closed - is recorded as the last step of the run. Complete, screenout and quota outcomes are configured as
  for any other survey system, with survey end page identifiers on the project. See
  [Survey end pages](https://www.surveytester.com/academy/en/company-admin-settings/survey-end-pages).

## Step by step

1. **Create the project.** Choose **Survalyzer** 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, rows and scale points.

## Good to know

- **Question names.** SurveyTester names the questions after Survalyzer's own question numbers, so the names stay the
  same in every language version of the survey: `single_65` for a single choice, `multiple_12` for a multiple choice,
  `m13` for a matrix, `open_36` for an open field. Answer values are the option numbers; a "not answered" option has
  the value `NA`.
- **Pages with several questions.** A page carries the name of its first question, or of its first and last question
  when it holds several.
