QUESTION $1$ Fill in the blank. Using $\_\_\_\_\_\_\_\_\_\_\_\_\_$ would be the re$-$execution of some subset of tests already conducted to ensure that no change has occurred from change made from further development. return testing Acceptance testing regression testing reoccurrence testing $2$ points QUESTION $2$ Smoke testing is typically applied after the software passes performance testing True False $2$ points QUESTION $3$ A Humidity Controller is a device that regulates the degree of humidity of water. The device is used in houses to keep humidity level at a healthy rate. The device controller works as follows If the level of humidity is in the range $[40\%,60\%],$ do nothing. If the level of humidity is higher than $60\%$ and the room temperature is cold or warm $($less than $25$ degrees$),$ do nothing. If the level of humidity is higher than $60\%$ and room temperature is $25$ degrees or higher, decrease humidity. If the level of humidity is lower than $40\%$ and room temperature is less than $25$ degrees, increase humidity. If the level of humidity is lower than $40\%$ and room temperature is $25$ degrees or higher, do nothing Restrictions: The device temperature sensor can read temperatures in the range $[-20,80].$ Temperature readings outside this range mean that the sensor is not working. In this case, the device screen should display $$Please check temperature sensor$$ Humidity level should be in the range $[0\%,100\%],$ readings outside this range mean that the humidity sensor is not working. In this case, the device screen should display $$Please check Humidity sensor$$ Using equivalence partitions, How many invalid test cases you need for testing the Humidity Controller? $121014162$ points QUESTION $4$ When you have logical relationships between inputs, which of the following approaches is more suitable? Equivelant Classes Equivelant Classes$/$ Boundary value analyisis Decision Tables Boundary value analyisis $2$ points QUESTION $5$ You can always prove that a program is correct if you test it enough and apply many different startegies True False
