Java ecosystem

The folks at ecosyste.ms have analyzed the structure of the open-source software community, grouping packages/projects into ecosystems, for funding purposes. Their "Java" ecosystem is the one I'm most familiar with: https://funds.ecosyste.ms/funds/java

From their list of 200+ "most critical packages", I extracted the ones I care most about: kotlin, junit4, slf4j, gson, guava, logging-log4j2, groovy, jna, jmh, jcommander, and findbugs. While hardly a representative sample, I'm concerned that several of these (junit4, jmh, and findbugs) appear to be unmaintained. I don't understand how sending money to Ecosystems Funds is going to improve these packages.

Jcommander, which I thought was unmaintained, proves on closer inspection to have a 2.0 release (from August) that I missed because it hasn't been uploaded to Maven Central.

Millionen Zeilen Code aber nicht einen Test. Wo startet man?

Eine berechtigte Frage, oder? Aber wie gehen wir am besten vor? Wir haben auf der einen Seite massiv viele Zeilen Code, aber eben keinerlei Test. Das genau ist in vieler Hinsicht schon ein massiver Fehler. Woher wissen wir eigentlich, dass der Source nicht massive Sicherheitsprobleme hat? Aus meiner Sicht ist es immer natürlich besser direkt mit dem Verständnis des Codes zu beginnen und eben mit der Codeanalyse auch gleichzeitig eine gewisse Spur von Expertise - Codeanalysen: Beginnt mit der Codeanalyse und dem Verständnis: Startet damit, die Architektur und Funktionalität des Codebestands zu verstehen. Dies könnte das Durchlesen von Dokumentationen beinhalten, falls verfügbar, sowie das Untersuchen des Codes selbst. Identifiziert kritische Bereiche, Module oder Funktionen, die für die ordnungsgemäße Funktion der Anwendung unerlässlich sind. - Identifiziert Hochrisikobereiche: Fokussiert euch auf kritische Funktionalitäten oder Module, die bei einem Ausfall wahrscheinlich den größten Einfluss haben. Sucht nach komplexen Algorithmen, Ein- und Ausgabevorgängen oder Bereichen, in denen Fehler am wahrscheinlichsten auftreten. - Priorisiert: Priorisiert die identifizierten Hochrisikobereiche für das Testen. Erwägt, mit Bereichen zu beginnen, die für die Funktionalität der Anwendung am wichtigsten sind oder in denen Fehler am wahrscheinlichsten auftreten. - Unittesting: Beginnt damit, Unittests für einzelne Funktionen oder Module zu schreiben. Unittests konzentrieren sich darauf, kleine Codeeinheiten isoliert zu testen. Wenn der Codebestand nicht für einfaches Unittesting strukturiert ist, erwägt eine Refaktorisierung, um ihn testbarer zu machen. - Integrationstesting: Sobald ihr Unittests implementiert habt, geht zum Integrationstesting über. Integrationstests konzentrieren sich darauf, wie verschiedene Teile des Systems zusammenarbeiten. Testet Interaktionen zwischen Modulen, Komponenten oder externen Abhängigkeiten. - Regressionstesting: Nach der Implementierung von Tests für kritische Bereiche solltet ihr Regressionstests hinzufügen, um sicherzustellen, dass neue Codeänderungen keine neuen Fehler einführen oder vorhandene Funktionalität beeinträchtigen. Automatisiert Regressionstests, wo immer möglich, um Probleme frühzeitig im Entwicklungsprozess zu erkennen.Kontinuierliches Testen und Integration: Implementiert eine Continuous Integration (CI)-Pipeline, um den Testprozess zu automatisieren. Dadurch werden Tests automatisch durchgeführt, wenn Änderungen am Codebestand vorgenommen werden. Integriert das Testen in den Entwicklungsworkflow, um euch dazu zu ermutigen, Tests für neuen Code zu schreiben und vorhandenen Code zu refaktorisieren, um ihn testbarer zu machen. - Codeüberprüfung: Integriert Codeüberprüfungen in den Entwicklungsprozess, um sicherzustellen, dass neue Codeänderungen gründlich getestet werden und bewährten Praktiken entsprechen. Ermutigt euch dazu, testbaren Code zu schreiben, und gebt Anleitungen zum Schreiben effektiver Tests. - Dokumentation und Wissensaustausch: Dokumentiert Teststrategien, bewährte Praktiken und spezifische Testfälle oder Szenarien. Teilt Wissen und Erfahrungen mit dem Testen im Team, um Testpraktiken zu verbessern und Konsistenz sicherzustellen. - Iteration und Verbesserung: Testing ist ein fortlaufender Prozess. Überwacht und verbessert kontinuierlich die Testabdeckung und -effektivität im Laufe der Zeit. Lernt aus Fehlern und passt die Teststrategie entsprechend an.  

Codeanalyse

  - Statische Codeanalyse-Tools nutzen: Nutzt statische Codeanalyse-Tools wie SonarQube, ESLint, Pylint oder FindBugs, um automatisierte Analysen des Codes durchzuführen. Diese Tools können potenzielle Fehler, Verstöße gegen Coding-Standards, Sicherheitslücken und andere Probleme identifizieren. - Manuelle Codeüberprüfung: Nehmt euch Zeit, um den Code manuell zu durchsuchen und zu verstehen. Beginnt mit den Hauptkomponenten und kritischen Bereichen. Stellt sicher, dass ihr die Dokumentation lest, um ein besseres Verständnis für das beabsichtigte Verhalten der Anwendung zu erhalten. - Reverse Engineering: Wenn möglich, verwendet Reverse-Engineering-Tools, um Diagramme oder Modelle der Codearchitektur zu erstellen. Dies kann helfen, komplexe Abhängigkeiten und Interaktionen zwischen verschiedenen Modulen oder Komponenten zu visualisieren. - Code Metriken: Verwendet Metriken wie Codekomplexität, Testabdeckung, Kopplung und Kohäsion, um die Qualität und Wartbarkeit des Codes zu bewerten. Dies kann euch helfen, Bereiche mit hoher Komplexität oder niedriger Testabdeckung zu identifizieren, die einer näheren Prüfung bedürfen. - Anforderungsanalyse: Stellt sicher, dass ihr die Anforderungen und das beabsichtigte Verhalten der Anwendung versteht. Vergleicht den Code mit den Anforderungen, um sicherzustellen, dass alle Funktionen ordnungsgemäß implementiert sind. - Prototyping und Experimentieren: Erstellt Prototypen oder führt Experimente durch, um das Verhalten bestimmter Teile des Codes zu testen oder zu verstehen. Dies kann helfen, Annahmen zu validieren und potenzielle Probleme frühzeitig zu identifizieren. - Kommunikation im Team: Diskutiert den Code und die Ergebnisse eurer Analyse mit anderen Teammitgliedern. Der Austausch von Meinungen und Perspektiven kann helfen, ein umfassenderes Verständnis für den Code zu entwickeln und potenzielle Probleme zu erkennen. Durch die Nutzung dieser Methoden und eine systematische Herangehensweise könnt ihr eine gründliche Codeanalyse durchführen und die Grundlage für die Einführung von Tests und die Verbesserung der Codequalität legen.

Unittests

Stellt klar: Unit-Tests sind nicht länger eine optionale Aufgabe. Zeitraum Alle Code-Änderungen werden jetzt getestet, je nach Bedarf neu oder aktualisiert. Die ersten Tests werden WIRKLICH schwer sein, da es am Anfang so viele Hürden gibt und die Lernkurve steil ist. Plant also vielleicht einen oder sechs Monate ein, um alle mit Schulungen, Präsentationen, Coaching und Nachhilfe darauf vorzubereiten. Um so streng zu sein (der gesamte Code muss jetzt getestet werden), müsst ihr zunächst mit mehreren Ebenen und Teilen der Organisation zusammenarbeiten, um die Leute vorzubereiten und mit den Ressourcen und dem Wissen auszustatten, das sie für eine so große Veränderung brauchen. Es kann leicht mehrere Monate dauern, bis eine solche Veränderung in Gang kommt, und ein bis drei Jahre, bis sie in Schwung kommt, sodass die Unternehmensleitung für einen langen Zeitraum bereit sein und ihre Erwartungen festlegen muss. Das Ergebnis ist ein modernes Unternehmen, das sich im Wettbewerb behauptet und gewinnt. Die Alternative ist der Untergang des Unternehmens. Phase 1 - Beginnen Sie mit der Einführung der Tests Schritt 1) Schreiben Sie einen „Wahr ist wahr“-Test. Schritt 2) Schreiben Sie einen Test „Aufruf einer einfachen Methode im Anwendungscode funktioniert“. Schritt 3) Schreiben Sie einen Unit-Test für eine einfache Methode, die alle Abhängigkeiten abbildet und ausblendet. Phase 2 - Anwendung der Tests auf die tatsächliche Entwicklung Für alle Code-Änderungen in der Zukunft: Schritt 1) Schreiben Sie Tests, die zusammen mit dem Code übertragen werden. Schritt 2) Schreiben Sie fehlgeschlagene Tests, bevor Sie den Anwendungscode schreiben. Schritt 3) Schreiben Sie Tests für den Rückstand der fehlenden Tests Machen Sie bei all diesen Schritten neben den Vorteilen auch die Schwierigkeiten deutlich. Verwenden Sie einen CI-Server, auf dem Ihre Zweige und Tests laufen. Wie circleCI zum Beispiel. Legen Sie die Innereien offen, um sie zu verbessern. „Tests zu haben hilft uns nicht wirklich, wenn wir keine Möglichkeit haben, sie auszuführen. „Das ist nur eine von Dutzenden Ausreden von Leuten, die nicht davon überzeugt sind, dass Testen eine wirklich tolle Sache ist - für Entwickler! Außerdem, seien wir ehrlich, MUSS ein Entwickler seinen Code irgendwie ausführen, um sicherzustellen, dass der glückliche Pfad tatsächlich ohne Syntaxfehler funktioniert. Niemand, den ich je gesehen habe, schreibt Code „blind“. Das Testen findet bereits statt, es wurde nur noch nicht formalisiert und automatisiert, das ist wahrscheinlich der Fall. Ich selbst habe früher Code ohne automatisierte Tests geschrieben (man kann wohlgemerkt sagen, dass ich ihn oft getestet habe), und zwar Millionen von Zeilen. Ihn zu ändern war schrecklich! Tests sind der beste Freund eines Entwicklers. Ich meine, wie kann man Code mit Zuversicht umgestalten - das Geheimnis der Qualität - wenn man keine Tests hat, die einen schützen? Der Anreiz, etwas zu verbessern, aber zu riskieren, etwas anderes kaputt zu machen, führt meiner Erfahrung nach dazu, dass überall Mist hinterlassen wird. Ist erst einmal ein Fenster zerbrochen, ist das Haus schnell zertrümmert (broken window theory). Es gelingt oft nicht, Menschen mit Argumenten umzustimmen, daher ist es wichtig, mit gutem Beispiel voranzugehen und Mitarbeiter zu gewinnen.   Read the full article

Techniques for Finding Errors in Your Java Code

Tips & Tricks for Java Code Reviews. Nobody can escape creating mistakes in their Java code from the start, sometimes not even experts. But you know what qualifies them as authorities? They are knowledgeable about shortcuts to cut down on errors and speed up their work.

So how do they spot Java code problems so quickly? What techniques will hasten the error-finding process?

As you continue reading, you will discover practical advice and shortcuts.

Top 6 Techniques for Finding Errors in Java Code

Tips & Tricks for Java Code Reviews. The following are the primary suggestions to identify errors in your Java code more quickly:

1. Go through the code first

To assist you identify the issue, run the complete code through. You may further reduce the issues as you develop solutions for a few by running the full code.

The scroll bar is used in the outdated approach to browse the code. The code may also be modularized, or broken down into manageable smaller components. You will be more able to identify sectional mistakes if you examine each element separately.

2. Examine the syntax highlighting

Common syntax mistakes include omitting a bracket or a semicolon, among others. A compiler can be used to detect syntactic mistakes. Reading the code in another language is another method for resolving syntactic issues.

Your job will be cut down by syntax highlighters, IDEs, and auto-indenting code. These IDEs or text editors are familiar with the syntax of the language. Additionally, they employ various colours for the keywords, strings, comments, and codes. Get acquainted with the highlighter's typical hues. In this manner, when a portion of the code has the incorrect colour, you may easily see syntax errors.

Use a Linter 3.

Developers can automate the code review process with the use of linters, which are simple static code analyzers. Using established coding conventions, they may identify defects, auto-fix style problems, and dubious constructions.

How does the lint roller function? The linter first examines the source code, checks for security flaws, and highlights coding mistakes. The code structure is then fixed to guarantee that maintaining the code is simple. In the end, they raise the overall quality and readability.

Work with Java developers

For linting, the Checkstyle tool performs really well. There are several tools available, including SolarLint,

Before employing a code review tool, run the entire code through the linter for analysis. If you go in this sequence, difficulties will be minimised.

4. Employ tools for Java code review

Use specialised Java code review tools to check the code before launching it. These instruments assess the source code's consistency. It also improves code quality by highlighting recurring errors like duplication and extraneous code elements. Code review is similar to document proofreading.

The collection of open-source, user-friendly code review tools compatible with Java is provided below. Among the tools are: • PMD, a review tool that is open-source and free. The PMD static analyzer, in addition to correcting the basic review flaws, finds IP addresses or passwords that render a website vulnerable to assaults. A copy and paste detector for PMD called CPD is adaptable to different computer languages.

• FindBugs is a free, open-source Java code review tool, just as PMD. The tool detects contradictions and alerts the developer. Additionally, the developer could make changes right away. However, the original Java tools operate the best with it.

• FineBugs has been upgraded to SpotBugs. It categorises errors and alerts the developer to them.

• The free utility Checkstyle finds design and formatting errors.

JArchitect examines the Java code for complexity and clarity, whereas Graudit aids engineers in identifying security vulnerabilities. It offers metrics for the code analysis.

Use a compiler, fifth

You may already be aware that a compiler may also detect grammatical problems. A compiler can be used to fix compile-time, run-time, and logic problems. For typos, unbound variables, and other errors of this nature, a compiler is fantastic.

Compiler finds problems at compile time and highlights the offending lines. It then displays an error message on the screen after noting the issue.

It's important to be aware that a compiler occasionally displays many error messages for a single issue. When this occurs, fix the first error before recompiling.

6. Debug!

A crucial competency for Java developers is debugging. The final irregularities that you missed after utilising code review tools are removed by debugging. By selecting Debug As from the context menu of the right-clicked Java editor class file in Package Explorer, you may debug. Utilizing the keyboard shortcut Alt+ Shift+ D is another option. You may also utilise the JDB, or Java Debugger, which on the platform debugs with a straightforward command.
