We can work on CS Mutation Testings

The problems are based on a simplified cruise control simulation program in Java. The zipped code file includes the following ten folders/packages: correct, mutant1, mutant2, …., and mutant9. The correct folder is the correct version, whereas each of the other folders contains a mutant of Controller.java. The finite state model of the Controller class is given below.

Round-trip tree
Use a computer-aided tool to draw the round-trip tree of the state model (20 points). Handwritten answer will not be accepted.
Write a Junit class ControllerRoundTripTest.java in the correct package to implement all the test cases from the round-trip tree. Each path from the root to a leaf should be implemented by a separate Junit test. Run ControllerRoundTripTest.java and none of the tests should fail, otherwise your tests are incorrect and you need to fix them before moving on to the next problem. Provide the source code of your ControllerRoundTripTest.java (15 points) and the screenshot of the test execution result (5 points)

Copy your ControllerRoundTripTest.java in Problem 1.2 to each mutantX (X=1, 2, …, 9) package. Make sure the package statement in ControllerRoundTripTest.java is correct so that you can test Controller.java in the same package. Summarize the test execution results in the following table and provide a screenshot of the test execution result for each mutantX (X=1, 2, …, 9). (5 points)

Sample Solution

…(download the remainder of the paper above 72. Joplin was a survivor of the sexual orientation generalizations of the stone business, and in the long run, ‘sexism executed her’ (Raphael, A. 2004), however she was a motivation to ladies and female craftsmen, for example, Tina Turner and Stevie Nicks began to show up in rock. Today, awesome music is still overwhelmingly ruled by men, yet Joplin’s impact brought forth a cultural move which gave ladies the leap forward they merited and picking up them a spot in the music business. The development of Poptimism saw ladies become the overwhelming focus in the business. With craftsmen, for example, Dua Lipa and Taylor Swift fixing US and UK graphs, ladies are overwhelming the pop scene. Ann Powers expresses that ‘ladies in music have consistently been related with pop – with attractiveness’ (Perry, C. 2011, in a meeting with Ann Powers). By and by, I concur with Powers; the pop business has transformed into an exceptionally sexualised sort. With progressions in innovation, music recordings have become some portion of what makes a tune so well known. Niki Minaj is a prime case of the effect of music recordings on progress. After some time, Minaj’s tasteful has changed, when she previously came into the music business, she was notable for her vocal capacities and her particular feeling of style; however as we follow her profession we see that the center has moved from her ability to her body. Minaj underscored this in her music video for ‘Boa constrictor’, in which she sexualised her body, demonstrating that having the perfect pop/rockstar picture is basic for accomplishment in the serious music industry. Obviously, Minaj is just a single model, and she is absolutely not the first. It is imperative to take note of that by and large, specialists will shape their own picture, notwithstanding, in different cases, record organizations and makers oppress people so as to sell.

Christian Anthony Goldsmith Meares Introduction: Definition of Prog Dynamic Rock was brought into the world off the rear of the counter culture development of the 1960’s – if not to some degree incidentally, the counter culture of the 60’s made its own counter – counter culture with artists who were increasingly focussed on making music which required progressively included tuning in. Dynamic stone (some of the time alluded to as “Workmanship Rock”, albeit ordinarily known by its shorter name “Prog”) is awesome music stylised by a more elevated level of multifaceted nature – odd time marks, less diatonic harmony structures, long melody structures and increasingly conceptual lyricism are frequently characterizing highlights of a prog tune. (Gibbs, 2018) Lord Crimson: Lyricism, Arrangement and the Mellotron As referenced above numerous muscicians started to search out progressively specialized music – “The entire thought behind prog was to help increase the creative decency of awesome” (Bonamassa, Joe, 2016). Artis 74. ts had become incresingly dissapointed by the straightforward popular music of the time, and musically opposed the thoughts related with awesome music. Accordingly, lyricism turned out to be substantially more otherworldly and had a dream feel to them, remnisicent of the hallucinogenic music of the late 60’s (Prog Archives, n.d.). This can honey bee seen on the early work of King Crimson, especially, “In The Court of the Crimson King”, what lyrics’ identity is’ soaked in a sentiment of sullen pretentiousness. Melodies like “Epitah” arrive at their peak near the brief imprint, with a rehashed verse of “I feel tomorrow I will be crying” trailed by an enormous guitar solo. This means another distinction to the awesome before the prog development – The plans are long with numerous parts, and there is a heavier accentuation on arrangement; on account of King Crimson this is fundamentally because of “[Ian Macdonald’s] unbelievable information to a limited extent composing in light of his [time spent] in the military working in a military band. (Tune to Soul, 2011) “The Court of the Crimson King” includes an orchestra of “strings” all through, and characterized one of the subgenres of prog – Symphonic Prog. The possibility that there is a genuine orchestra orcherstra on this collection, nonetheless, is a dream, made by one of the enormous specialized insurgencies of the time – The Mellotron. The Mellotron was one of the main samplers – with a comparative appearance to a console, when a key was squeezed tape with recorded sound was played, until the key is discharged, which is the point at which the tape is pulled back to the beginning position. This permitted Ian Mcdonald and Robert Fripp, establishing individuals from King Crimson, to investigate diverse instrumentation. (Ian McDonald Conversations on Mellotrons>
