A test manager has started a cycle of testing for an e-commerce application. The reason for testing is the change in the protocol for connecting to the payment gateway because of new regulations. Which of the following correctly names this type of testing?
Consider the followinguser storyand itsacceptance criteria:
User Story:
As a member of the"Agnotoly"association, I want to be able topay the association’s dues through an automatic payment methodso that I can forget about payment deadlines.
Acceptance Criteria:
The member can only pay with‘Agnesis Master’ credit card.
The member must register theircell phone number.
The member must register thecredit cardin the payment system.
The member must select apayment method (monthly or annual).
The member mustaccept the terms and conditionsfor the selected method.
If terms and conditions are accepted, the system sends anOTP(one-time password) to the member’s phone for verification.
The payment method isregistered only after OTP verification.
Once the payment method is registered, the system will charge on the first business day of the following month.
Test Cycle Results:
Members successfully paid dues using the credit card.
Payments were processedmonthly and for over a year.
Which ONE of the following options identifies the acceptance criteria that has NOT been fully covered?
A program is used to control a manufacturing line (turn machines on and off. start and stop conveyer belts, add raw materials to the flow. etc.). Not all actions are possible at all times. For example, there are certain manufacturing stages that cannot be stopped - unless there is an emergency. A tester attempts to evaluate if all such cases (where a specific action is not allowed) are covered by the tests.
Which coverage metric will provide the needed information for this analysis?
The following chart represents metrics related to testing of a project that was competed. Indicate what is represented by tie lines A, B and the axes X.Y
A)
B)
C)
D)
Which ONE of the following options MOST ACCURATELY describesstatement testing?
A number of characteristics are given for impact of SDLC on the testing effort.
i.Finishing of requirements review leading to test analysis
ii.Both - static and dynamic testing performed at unit testing level
iii.Frequent regression testing may need to be performed
iv.Extensive product documentation
v.More use of exploratory testing
Which of the following statements is MOST correct?
Which of the following is a role that is usually responsible for documenting the findings (e.g., action items, decisions, recommendations) made by the review team as part of a typical formal review?
A new web app aims at offering a rich user experience. As a functional tester, you have run some functional tests to verify that, before releasing the app, such app works correctly on several mobile devices, all of which are listed as supported devices within the requirements specification. These tests were performed on stable and isolated test environments where you were the only user interacting with the application. All tests passed, but in some of those tests you observed the following issue: on some mobile devices only, the response time for two web pages containing images was extremely slow.
Based only on the given information, which of the following recommendation would you follow?
Which of the following is a factor that contributes to a successful review?
Which ONE of the following statements about the objectives of confirmation and regression testing is the BEST?

Based only on the given information, which of the following statements is true?
In a two-hour uninterrupted test session, performed as part of an iteration on an Agile project, a heuristic checklist was used to help the tester focus on some specific usability issues of a web application.
The unscripted tests produced by the tester's experience during such session belong to which one of the following testing quadrants?
Consider the followingiteration planning taskswhere a tester can provide value:
Break down user stories into tasks (particularly testing tasks)
Estimate test effort for all testing tasks
Identify and refine functional and non-functional aspects of the test object
Which ONE of the following tasks should be ADDED to the above list?
The following rules determine the annual bonus to be paid to a salesman of a company based on the total annual amount of the sales made (referred to as TAS).
If the TAS is between 50k€ and 80k€, the bonus is 10%. If the TAS exceeds 80k€ by a value not greater than 40k€, the bonus is 15%. Finally, if the TAS
exceeds the maximum threshold which entitles to a 15% bonus, the bonus is 22%.
Consider applying equivalence partitioning to the TAS (Note: 1k€ = 1000 euros).
Which one of the following answers contain only test cases that belong to the same equivalence partition?
