Multi-step operations

Record and manage multi-step operations that are required to reach specific parts of the application that could otherwise be missed.

A multi-step operation is needed to explore parts of the site that can only be reached by clicking links in a specific order, such as an online shop where the user adds items to a cart before paying for them. Consider the following three pages:
  1. User adds one or more items to a shopping cart
  2. User fills in payment and shipping details
  3. User receives confirmation that the order is complete
Page 2 can only be reached via Page 1. Page 3 can only be reached via Page 1 followed by Page 2. This is a sequence. In order to be able to test Pages 2 and 3, AppScan® must send the correct sequence of HTTP requests before each test.

In the case of the above example, you would record a single sequence: Page 1 > Page 2 > Page 3. AppScan® would extract the necessary sub-sequences from this sequence, as required. (When testing Page 2, it would send a Page 1 request first; when testing Page 3, it would send Page 1 followed by Page 2.)

Note: It is suggested that you limit the number of multi-step operations to five, with no more than 25 steps in any single operation, and no more than 70 steps altogether.
Note: Configuring multi-step operations should not be confused with manual exploring and should only be used in cases like the one described above. For more details, see Manual Explore using AppScan

Lists all recorded multi-step operations for this scan.

Sequence name

The name of the sequence that is selected in the List of Sequences. The check box next to each one indicates if the sequence is enabled for this scan.

Export

Export the selected sequence as a SEQ file to use in a different scan.

Record

Click to record a new sequence. If you have configured login details, you can click the down arrow to select:
AppScan Chromium browser (default)
AppScan will record using the built-in Chromium-based browser, without logging in. When the browser opens you can log in, if needed, and then record your multi-step sequence.
Note: If you use this option and then record login requests as part of the sequence, parameters and cookies received will always be treated as Dynamic, even if they are Login requests, and even if you change their tracking to Login Value.
External browser
Active only if you have configured AppScan to use an external browser for scanning (Tools > Options > Use External Browser > Select Browser). If possible it is recommended to use the AppScan Chromium browser, as it records extra information that improves login success during scanning. Use the external browser only if recording the login with the AppScan browsers does not work for your application.

Playback Method

When you record a multi-step operation, AppScan records both the actions and the requests. You can select which of them will be used for the scan:
Request-based playback
Sends the raw HTTP requests from the recording. This method is usually faster.
Action-based playback
Replays the clicks and keystrokes of the user. Reasons for selecting this method could be that the site includes a lot of JavaScript, or that some of the requests in the request-based playback were marked with a red X when you attempted to validate them. This method can increase scan time.
Request-based playback is the default method.
Note: If the scan is configured not to use a browser other than the embedded browser (Tools > Options > Use external browser), request-based playback is always used.
Note: If you load a sequence that was recorded in a version of AppScan that did not support action-based playback, request-based playback is used for that sequence, even if action-based playback is selected.
Note: If you select Action-based playback for a multi-step operation, you must also select Action-based as the login method. If necessary, record the Login sequence again (see Login management).

Sequence List

Lists all recorded Multi-Step Operations for this scan.

Sequence Name

The name of the sequence that is selected in the List of Sequences. The check box next to each one indicates if the sequence is enabled for this scan.

Validate
Click this to check that the sequence is valid. AppScan replays the sequence, and any requests that receive a response different to the original response are marked with a red X, indicating that they will not be tested.
Tip: A common reason for requests receiving a different response is the presence of a dynamic sequence variable that needs to be defined, see Sequence variables. If this is not the problem, and the site contains JavaScript, changing to action-based playback may give better results.

Recorded URLs

Shows the links or actions in the selected sequence.

Validated
A green check mark indicates that the URL has been validated. A red X appears next to URLs that were not validated.
Test
Indicates whether this URL will be tested on its own (as well as in the Multi-Step Operation). Options are Yes/No. To change the setting, right-click on the URL and select Test / Don't Test. Even if you select No, the URL will still be played as part of the Multi-Step Operation.
Play Sequence
(Applies to tested URLs only) Indicates whether the previous steps in the sequence will be replayed each time this URL is tested. Options are Yes/No. To change the setting, right-click and select Play sequence before testing request > Yes/No.
  • View any link in the sequence by selecting it and then clicking the browser button (you can delete individual requests by clicking the trash icon in the upper right of the dialog that opens)
  • Delete any link in the sequence by selecting it and clicking minus button. After doing this, click Validate to check that the updated sequence stays in-session.

Log in before sequence replay

If selected, each time a Multi-Step Operation is played, AppScan will log in first. This option is cleared if you record the login as part of the multi-step operation.

Allow play optimization

(Request-based playback only) When selected (default), AppScan® attempts to optimize scan time by avoiding unnecessary playback. You should not disable this setting unless you find that AppScan® is missing parts of the application due to play optimization. The Scan Log can help in determining this.

Test in Single-Thread mode

AppScan® may send two or more requests simultaneously if they don't require the replaying of a sequence between them. If this results in parts of the application being missed, select this check box.

Sequence Variables

Lists variables that were received while recording the sequence(s) and indicates those that AppScan® has determined should be tracked. These may be session IDs or other variables. You can change the status of variables in this list to improve how AppScan® deals with them (for details, see Sequence variables).
