Adding Scenarios from GUI

User needs to follow the below mentioned steps for adding scenario:

  1. Login to NetCloud, the NetCloud home page is displayed.

  1. Go to View > Scenarios > Scenarios or click Total Scenarios in the “Test Assets Summary” section in the right pane. The Scenario Management window is displayed.

3. Scenario can be created in two ways, one is via wizard and another one via Advance settings. First, scenario creation via wizard is described. In the next section, scenario creation via advance settings is described.

Scenario Creation via Wizard

Scenario creation using wizard is a step by step approach for scenario creation with a series of screens. Follow the below mentioned steps for scenario creation using wizard:

  1. Click the Wizard button on the scenario window, the welcome screen of scenario configuration wizard is displayed.

2

2. Post few seconds, various steps for scenario creation is displayed. At first, only the initial step is enabled. Rest other are enabled sequentially on the completion of each step only.

Step – 1: Scenario Name

In this step, user needs to select the project and subproject under which the scenario is to be created. Post that, specify a valid scenario name. First character must be alpha, other characters can be alpha, numeric, dash or underscore. Then, click the Next button to move to the next step.

Step – 2: Scenario Profile (Optional)

In this section, user can select an already created scenario profile (how to create a scenario profile is discussed later). NetStorm has scenario profiles to keep default configurations specific to a subproject at a commonplace. To use a scenario profile, select the Use Scenario Profile for Scenario Settings checkbox and specify the project, sub-project, and profile name. Then, click the Next button to move to the next step.

Step – 3: Add Generator

In this step, user needs to add generator(s) for scenario groups. Select one or more generators from the list. To add all the generators, select the Use all Selected Generator(s) for all scenario group(s) check box.  Click the Next button to move to the next step.

Step – 4: Scenario Group  

Select the Scenario type, either Fix Concurrent Users (FCU) or Fixed Session Rate (FSR). Specify the script from the drop-down list and mention the number of users (in case if FCU is selected) and number of sessions per minute (in case FSR is selected). User can add more records using the Add button. Then, click the Next button to move to the next step. Below is an example of FCU, where 10 users are added in group G1 and 20 users are added in group G2. All generators are selected for both the groups.

Step – 5:  Ramp Up

The Ramp-up phase signifies the action of mounting any sort of operation. This phase is needed, so that in test execution of a scenario, users are ramped by spacing them appropriately. This ramping up reduces overload on Servers.

FCU

Ramp-up can be done by any of the four ways:

  • Immediate Ramp-up

Selecting the Simultaneously option results in all virtual users of the Virtual Group to access site Immediately. This is called Immediate Ramp-up. For example, 80 Virtual users access site instantly for a group.

  • Stepwise Ramp-up

Select a specific number of Virtual users to repeatedly access a site after inserting a time delay (in HH:MM:SS). The users are ramped up in steps. For example, 25 Virtual users are ramped-up followed by next 25 after a delay of 5 seconds, till all 100 are ramped-up.

  • Time Mode Ramp-up

All Virtual users access site after inserting time delay (in HH:MM:SS). This is called Time Mode Ramp-up. For example, 100 Virtual users ramp-up after inserting time delay of (HH:MM:SS). This Time Mode Ramp-up can be further achieved by 2 modes.

    • Linear Time Mode Ramp-up

Users ramp linearly means that the users are created at a constant inter arrival time. All Virtual users access site after inserting a time delay (in HH:MM:SS). System decides to pick a fixed number of users to Ramp-up. For example, System decides to Ramp-up 25 users after every 5 seconds till all 100 users are ramped-up.

    • Random Time Mode Ramp-up

All Virtual users access site after inserting a time delay (in HH:MM:SS). System decides to pick a fixed number of users randomly to Ramp-up. For example, System decides to Ramp-up 20 users after every 5 seconds then ramps up 30 after delay of further 5 seconds and later ramps up 10 users and so on till all 100 users are ramped-up.

  • Rate Mode Ramp-up

Specify a fixed number of Virtual users to ramp-up per Second/per Minute/per Hour.  This Rate Mode Ramp-up can be further achieved by 2 modes:

 Note These options are activated by deselecting the Default Rate check box.
    • Linear Rate Mode Ramp-up

Users are created at a constant inter arrival time. Specify a fixed number of Virtual users to ramp-up per Second/per Minute/per Hour. System decides to pick a fixed number of users to Ramp-up. For example, 20 Virtual users ramp-up followed by delay per 1 second, next 20 users ramp-up and after further 1 second delay, 20 more users ramp-up and so on.

    • Random Rate Mode Ramp-up

Specify a fixed number of Virtual users to ramp-up randomly per Second/per Minute/per Hour.  System decides to pick random number of users randomly to Ramp-up. For example, 20 Virtual users ramp-up followed by delay per 1 second, next 30 users ramp-up and after further 1 second delay, 10 more users ramp-up and so on.

 Note The default rate is 120 users per minute for our system.

 

FSR

There are following options under this section:

  • Immediate Ramp-up

Selecting the Simultaneously option results in all virtual users of the Virtual Group to access site Immediately. This is called Immediate Ramp-up. For example, 80 Virtual users access site instantly for a group.

  • Time based Ramp-up

All Virtual users access site after inserting time delay (in HH:MM:SS). This is called Time Mode Ramp-up. For example, 100 Virtual users ramp-up after inserting time delay of (HH:MM:SS). This Time Mode Ramp-up can be further achieved by 3 modes:

    • Default Steps: Using this option, a pre-configured steps (i.e. 2) are applied for the sessions’ completion.
    • Steps of specified seconds: Using this option, user can specify the duration for each step.
    • Number of specified steps: Here, user can specify the number of steps to complete a session.

Step – 6: Duration

The Duration phase signifies the time for which the process runs without any change in any settings.

FCU

This Duration phase can further be achieved by 3 modes:

  • Time Mode Duration Phase             

This Time Mode duration phase means that the Scenario runs for a specific defined time. Select the Run for option and specify number of days and time delay in (HH:MM:SS). For example, 100 Virtual users accessing a site remain there for 1 day, 01:12:24, i.e., 01 hour, 12 minutes & 24 seconds.

  • Session Mode Duration Phase

This Session Mode duration phase means that the Scenario runs for a specific number of sessions. For example, 100 Virtual users accessing a site run for 10 sessions.

  • Indefinite Mode Duration Phase

In this phase, the Scenario doesn’t stop if Run Indefinite mode is selected. For example, 100 Virtual users accessing a site remain there for indefinite time.

 Note This is the default option.

FSR

There are following options under this section:

  • Time Mode Duration Phase             

This Time Mode duration phase means that the Scenario runs for a specific defined time. Select the Run for option and specify number of days and time delay in (HH:MM:SS). For example, 100 Virtual users accessing a site remain there for 1 day, 01:12:24, i.e., 01 hour, 12 minutes & 24 seconds.

  • Indefinite Mode Duration Phase

In this phase, the Scenario doesn’t stop if Run Indefinite mode is selected. For example, 100 Virtual users accessing a site remain there for indefinite time.

 Note This is the default option.

Step – 7: Ramp Down

The Ramp-down phase means a gradual decrease in number of Virtual Users from system. This is reverse of Ramp-up Phase.

FCU

Ramp-Down can be done by any of the three ways:

  • Immediate Mode Ramp-Down Phase            

Selecting the Simultaneously option results in all virtual users to be removed from the site Immediately. For example, 100 Virtual users accessing a site are removed from the system immediately.

  • Step Mode Ramp-Down Phase

Select a specific number of Virtual users to repeatedly removing from the system after a time delay (in HH:MM:SS). For example, 25 Virtual users are ramped-down followed by next 25 after a delay of 5 seconds, till all 100 users are removed from the site.

  • Time Mode Ramp-Down Phase

All Virtual users are removed from system after a time delay (in HH:MM:SS). This Time Mode Ramp-Down can be done by any of the two ways:

    • Time Mode Ramp-down – Linearly

All Virtual users are removed from system after inserting time delay of (HH:MM:SS) in a Linear mode. System decides to pick a fixed number of users to Ramp-down. For example, System decides to Ramp-down 20 users after   every 5 seconds and so on till all 100 users are ramped-down.

    • Time Mode Ramp-down – Randomly

All Virtual users are removed from system after inserting time delay of (HH:MM:SS) in a Random mode. System decides to pick a fixed number of users to Ramp-down. For example, System decides to Ramp-down 20 users after every 5 seconds, followed by 10 users in next 5 seconds followed by 30 users ramped down in next 5 seconds and so on till all 100 users are ramped-down.

FSR

There are following options under this section:

  • Immediate Mode Ramp-Down Phase            

Selecting the Simultaneously option results in all virtual users to be removed from the site Immediately. For example, 100 Virtual users accessing a site are removed from the system immediately.

  • Time based Ramp-down

All Virtual users are removed from system after a time delay (in HH:MM:SS). This Time Mode Ramp-down can be further achieved by 3 modes:

Default Steps: Using this option, a pre-configured steps (i.e. 2) are applied for the sessions’ completion.

Steps of specified seconds: Using this option, user can specify the duration for each step.

Number of specified steps: Here, user can specify the number of steps to complete a session.

Step – 8: Page Think Time

Page Think Time is the Page View Time (after a page is downloaded).

FCU and FSR

There are following options under this section:

Think Time Options

  • No Think Time: No time is spent in viewing the pages. This is the default option selected. 
  • Random (Internet type distribution) think time with median of value specified in seconds: The think time is taken randomly in internet type distribution pattern with median of the value specified. For internet type distribution, median is roughly around ¼th of the mean.
  • Constant think time of value specified in seconds: By selecting this option, constant think time can be taken for each page. The time needs to be specified in seconds.
  • Random (Uniform distribution) think time from specified range in seconds: It randomly takes the value of think time from the range specified in uniform distribution.
  • Custom think time returned by C method: Enter the method name.

Override Recorded Think Time

This setting overrides the setting of the page think time for the particular pages. To override recorded think time, following options are available:

  • Use recorded think time: If user selects this option, the default think time of the script is applied.
  • Multiply recorded think time by some value: On selecting this option, user has to provide some value (number) so that the given page think time is multiplied by the value provided in this textbox. By default, it is 0. 
  • Use random percentage of recorded think time: On selecting this option, user needs to provide the minimum and maximum % value so that the page think time is in between the minimum and maximum % of the above provided page think time.

Step – 9: Session Pacing

Session pacing is an interval between two sessions executed by a virtual user.

FCU

There are following options under this section:

Start New Session

This specifies when the next session is started after a VUser completes previous session. It can have one of the possible values:

  • As soon as the previous session ends: The new session begins as soon as possible after the previous iteration ends. This mode is good for loading the SUT maximally. (This is the Default mode)
  • After the previous session ends: The new session starts after the end of previous session. There are following options:
    • With fixed delay: The next session is started after a fixed delay. Specify the delay in seconds.
    • With random (Internet type distribution) average delay: The delay is random average delay of the time specified in seconds.
    • With random (Uniform distribution) delay: The delay is of random but uniform distribution and within the range specified in seconds.
  • Once every interval (Provided that the previous session ends by that time else next session starts as soon as previous session ends):
    • At fixed interval: The next session starts after a fixed interval of time specified in seconds.
    • At random (Internet type distribution) average interval: The delay is random average delay of the time specified in seconds.
    • At random (Uniform distribution) interval: The delay is of random but uniform distribution and within the range specified in seconds.

Example: Consider a situation where previous session took 10 seconds and user has pacing time of 15 seconds. In this case, next session would be started after 5 seconds of completing the last session. This mode tries to keep the average session rate same even if the server response time changes. This is more similar to real life situations where the typical session rate (sessions/hours) does not change for an application if the response time is increased. If the last session takes more than pacing time, next session would be started immediately after completing previous session.

Introduce delay before first Session too (By randomized mean pacing time): By enabling this check box, a delay can also be applied before start of first session. This delay is calculated by randomized mean pacing time.

Simulate a new user on each session: By selecting this option, a new user is simulated on each session.

    Ensure that URL is ended by forward slash “/”.

     

    • JMeter Script: JMeter test can be run from NC test by running JMeter instance from NetCloud. JMeter instance runs its own JMXscript. NetCloud reads data from JMeter logs and plotting HTTP graphs on dashboard.

     

    • RDT URLs: NetCloud / RDT provides a versatile mobile application testing platform using real iOS and Android devices on cloud. NetCloud / RDT has the largest device farm of real mobile devices, gathered from different regions globally, including the most versatile OS, OEM and hardware configurations for Android and iOS developers. This helps in test automation, remote manual access and REST API to access, run and manage any tests with these devices.

To delete more than one generator at once, select the check boxes against the generator names, and then click the Delete icon  at the upper-right corner of the window. To delete all the generators at once, select the topmost check box.

A confirmation message is displayed to delete the selected generator(s). Click OK.

Continue test on generator failures

By selecting the check box, the user can continue to run the test even if the generators fail to start. These are the following options under this section:

Minimum percentage of healthy generators needed for test to start: The user needs to provide the minimum percentage of generators that are required to run the test.

Minimum percentage of healthy generators during a test: This percentage of generators decides whether the controller continues or fails while the test is running.

Stop test on generator if connection with controller does not establish in: In case of the test triggered on generator, the user needs to provide the time (in seconds) for which the controller must wait for the generators to start test.

Stop test on generator if missed progress samples equal: The user needs to provide the number of progress samples. The test on generator stops if it is unable to send this number.
