Your organization's test strategy states that it is desirable to usemore than one method for estimating test effort. You are responsible for estimating test effort for the next project. Based on historical data, the development-to-test effort ratiois5:3.
The initial estimate for thedevelopment effort is 450 person-days.
Which ONE of the following options corresponds to the estimatedtest effortusing the ratio-based method?

Scenario 1 "Happy Tomatoes" (used for questions 20-22):
An intelligent application for agricultural use incorporates temperature sensors located at different points of an enclosure. The sensors measure and record the temperature at regular intervals and extract the statistical values for these measurements. These values include the average daily temperature.
A new variety of tomatoes is currently being grown and the"World Organization for Happy Tomatoes"has established temperature ranges related to vegetative development.
When the system establishes that the average temperature is within a specific range, it emits a value that will be used to monitor and control the crop.
Using theequivalence partitioningtechnique, identify the set of input values that provides the HIGHEST coverage.

You are testing a system that is used in motor vehicles to warn the driver of an obstacle when re-versing.
Output is provided by a series of LED lights (green, yellow, and red), each illuminated based on clearly defined conditions.
The following summary describes the functionality:
*Object within 10 metres, green LED lit.
*Object within 5 metres, yellow LED lit.
*Object within 1 metre, red LED lit.
*Setting sensitivity mode to "ON" will result in only the red LED being lit when the object is within 1 metre.
The following decision table describes the rules associated with the functioning of this proximity warning system:
Which intended functionality is tested by Rule 5 in the decision table?

A requirement specifies that if the total amount of sales (TAS) made during the year by a corporate seller is
300,000€ or more, the bonus that must be paid to the seller is 100% of a certain amount agreed upon at the beginning of the year. The software contains a fault as it implements this requirement with the decision "IF (TAS = 300,000)" instead of "IF (TAS >= 300.000)". The application of the 3-value boundary value analysis to this problem consists of the following three test cases (TAS is an integer variable):
TC1 = 299,999 TC2=300,000 TC=300,001
Which of the following statements is TRUE?
