Sabbin karya sun fito a matsayin zaɓi mai dacewa da lokaci don masu haɓakawa suna gwada lambar su, lokacin da basu da damar zuwa sabar na ainihi. Waɗannan sabobin sune ainihin simulations na sabar na ainihi, ana amfani da su wajen haɓakawa da gwaji, kuma suna aiki azaman kayan aiki mai mahimmanci a cikin arsenal na ci gaban yanar gizo.

The Magani

Maganin ga matsalar rashin samun damar uwar garken yayin yin codeing ko gwaji sabar karya ce. Don fahimtar wannan mafita, yana da mahimmanci a fahimci rawar uwar garke a cikin haɓaka gidan yanar gizon. Sabar shine ainihin mahallin da ke amsa buƙatun daga na'urorin abokin ciniki, tare da martanin da suka dace. Misali, a cikin yanayi na yau da kullun, abokin ciniki na iya aika buƙatu don wani shafin yanar gizon, wanda uwar garken sannan ya ba da.

Koyaya, yayin haɓaka lambar, ƙila masu haɓakawa ba koyaushe suna samun damar zuwa sabar masu rai ba. Ko saboda rashin kayan aiki ko kuma rashin samun sabar kai tsaye yayin yin codeing, masu haɓakawa suna buƙatar hanyar gwada lambar su. Wannan shine lokacin da uwar garken karya ya shigo - yana aiki azaman “simulator” ko “tsayawa” don sabar ta gaske.

Bayanin mataki-mataki na Code

Don kwatanta yadda a uwar garken karya yana aiki a JavaScript, bari mu yi tafiya ta wasu sauƙaƙan pseudocode.

 

```JavaScript
// First, we need to create an instance of a fake server
var server = sinon.fakeServer.create();

// Then, let's stipulate how the server should respond
server.respondWith("GET", "/some/endpoint", [200, {}, "Hey there!"]);

// We then have the server respond automatically
server.respond();

// Lastly, we restore the server to its previous state once we're done testing
server.restore();
```

Bari mu rushe abin da lambar ke yi a cikin tsari-mataki-mataki:

• Mataki na farko yana fara sabar sabar karya ta amfani da Sinon.JS, ƴan leƙen asirin gwaji, stubs, da izgili ga JavaScript.
• Na gaba, mun ayyana yadda uwar garken zata amsa buƙatun GET zuwa wani wurin ƙarshe.
• Sai mu gaya wa uwar garken don fara amsa buƙatun.
• A ƙarshe, da zarar an gama gwajin mu, za mu mayar da uwar garken don dawo da komai zuwa yanayinsa na asali.

Dakunan karatu da Ayyuka

A cikin snippet code da aka ambata, mun yi amfani da su Sinon.JS, sanannen ɗakin karatu don gwajin ƴan leƙen asiri, stubs, da izgili a cikin JavaScript. Sinon yana ba masu haɓaka damar sarrafa ayyuka da halayen su a cikin gwaje-gwajen su. A cikin wannan mahallin, mun yi amfani da shi don ƙirƙirar sabar karya ba tare da matsala ba.

The aiki sinon.fakeServer.create() yana haifar da misalin sabar karya yayin uwar garken.respondDa() hanya ce da ke nuna yadda uwar garken zata amsa duk wani buƙatun mai shigowa. Aikin uwar garken.respond() yana jawo uwar garken don fara amsa buƙatun masu shigowa. Daga karshe, uwar garke.restore() ana amfani da shi don mayar da uwar garken zuwa matsayinsa na asali.

Kyakkyawan uwar garken karya shine cewa ana iya daidaita sigogi don amsawa kamar yadda ake buƙata, ba da damar masu haɓakawa su gwada lambar su akan martanin uwar garken iri-iri. Kyakkyawan JavaScript da dakunan karatu irin su Sinon.JS shine cewa suna ƙarfafa masu haɓakawa don ƙirƙirar waɗannan wuraren gwaji cikin sauƙi da inganci.
