CSECUTA The Testing Project CSE 4321 Motivation · Provides an opportunity to practice the basic concepts, principles, and techniques covered in this course . Specifically, you will apply control flow testing to a program of moderate size - Printtokens.java: a Java class that implements a string tokenizer (available in Canvas). - about 500 lines of code with seeded faults CSECUTA - Both members will receive the same grading. Input and Output · Input - Location of a file (i.e., input to the main() method) that contains the tokens to be classified - If a location is not given, the user is expected to type the tokens to be classified on the console. · Output - Type of each token, one per line CSE 4321, Jeff Lei, UTA CSECUTA Type of Tokens · Keyword: and, or, if, xor, lambda, => . Special Symbol: "(", ")", "[", "]", "" ,"", '," (Iparen, rparen, lsquare, rsquare, quote, bquote, comma) · Identifier: begins with a letter and contains only letters and digits, e.g., a, aa, a1, a2. · Number Constant: e.g., 123, 1, 321 · String Constant: e.g., "asd", "123" · Character Constant: e.g., #a, #b, #c, #d . Comment: Anything starts with ";" CSE 4321, Jeff Lei, UTA CSECUTA • Error: Everything else Example test.txt 1 and` and 2 j Input: 3 112A Arguments: C Main (x)= Arguments JRE Deper Program arguments: "./test.txt" CSE 4321, Jeff Lei, UTA CSECUTA Problems @ Javadoc Declaration Console X Printtokens2 [Java Application] /Library/Java/JavaVirtualMachines keyword , "and". bquote. keyword, "and". identifier,"j". Output: error, "112A". Major Steps Create the Control Flow Graph (CFG) for each method • - The code in the catch clauses can be skipped, i.e., these clauses do not need to be represented in the CFG . Unit Testing: For each method other than the main method, select a set of test paths to achieve edge coverage, i.e., cover all the edges in the CFG of the method CSE 4321, Jeff Lei, UTA CSECUTA • Program Testing: For the main method, select a set of test paths to achieve edge coverage for the entire program, i.e., cover all the edges in all the CFGs. • Generate test cases, including test data and expected output, for each test path - If a test path you selected in the previous step is infeasible, a new test path needs to be selected . Use JUnit to implement and execute the generated test cases. · Provide edge coverage reports for tests executed. - One report for the unit tests of individual methods, and one report for the program-level tests of the main method Deliverables . Due date (FIRM): July 3 (midnight, last day of class) CSE 4321, Jeff Lei, UTA CSECUTA . 20%: CFGs along with the corresponding source code, and the basic block table that identifies each basic block . 30%: Test cases, including each test path, the corresponding test data to execute the test path, and the expected output . 25%: JUnit source code · 5%: Code coverage reports . 10%: Faults detected and corrections · 5%: Summary and discussion. . 5%: A ReadMe file that explains how to execute your JUnit code CSE 4321, Jeff Lei, UTA CSECUTA Must-Have Files . Your project should be submitted in GitHub Classroom · Must contain these but not limited to these files. - CFG.pdf - Test Cases.pdf - Source Code - Code Coverage Reports.zip - Faults and Corrections.pdf - Summary and Discussion.pdf - ReadMe.txt · Typed reports are strongly recommended; if you choose to handwrite and scan the reports, it is your responsibility to ensure legibility. CSE 4321, Jeff Lei, UTA CSECUTA Evaluation · Faults detected and code coverage are not the main focus of our evaluation. . If you follow the approach correctly, you could expect to detect at least 10 bugs. . Focus on the "approach", instead of the "faults" Recommendations . IDE: Eclipse; Code Coverage: JaCoCo/EclEmma CSE 4321, Jeff Lei, UTA CSECUTA - Refer to the video titled "Get started with the project" in Canvas - Other tools could be used, but you may be asked to give a demo for the TA . When you find a fault, fix it before you continue. This could help to discover more faults. . If fixing a fault alters the control flow, you are not required to construct a new CFG. . Do not try to use CFG generation tools for Java programs; otherwise, you will receive no points on the project. - Many tools generate CFGs based on byte code, not source code. The output could be incorrect w.r.t the project specification. CSE 4321, Jeff Lei, UTA
